strongest fishing magnet

Magnet fishing

In order to find metal objects in bodies of water, magnet fishing uses strong magnets called “fishing magnets,” which is similar to metal detecting. Have you ever wondered what might be submerged beneath a nearby lake? One way people have tried to find out is by affixing a magnet to the end of a rope and they have made some fascinating discoveries. We are going to look at the strongest fishing magnet in this article.

Anyone can enjoy and join in the outdoor activity of magnet fishing, which offers outdoor enthusiasts a distinctive way to interact with their environment. Imagine the excitement of exploring an unusual aquatic location where you suspect something extraordinary may be lurking, the satisfaction of pulling some metal treasure from the water, and the opportunity to see what lies “below the surface.”

For your magnet fishing setup and equipment, you will require a few things. A strong magnet serves as the hook and sinker in magnet fishing, just like in traditional fish angling, while a rope attached to the magnet serves as the line. You need to magnet fish in the appropriate locations to increase your chances of finding metal, which requires a lot of patience. In contrast to fish angling, magnet fishing produces speedier results in terms of catching anything; you’ll know right away if there is any metal lurking below the surface and will be able to reel it in when you feel the magnet stick to something.

Powerful magnets are required for magnet fishing. The strongest magnet you can get should be attached to a strong rope. Remember that the metal object must lie fully flat on the magnet for the magnet’s draw force to be at its maximum. Since objects that have been at the bottom of a lake for a long time have a tendency to collect debris and the metal object itself may not be flat, flat contact is difficult to achieve when magnet fishing, so the strongest magnet is advised. It’s important to keep in mind that larger discoveries will need a stronger magnet to be extracted from their resting place.

Neodymium magnets

Neodymium is most commonly used in an alloy with iron and boron to create extremely powerful permanent magnets.  These aren’t your typical fridge magnets. Even if you’ve never heard of a neodymium magnet, you probably use them every day because they are the strongest permanent magnets currently on the market. They are frequently referred to as neo magnets and are preferred for a number of applications because of their strength despite being lightweight.

The neodymium magnet is very strong. Over 1700g of force is produced by a 2-gram neodymium magnet that is 8mm in diameter and 5mm long. Since neodymium magnets are nearly 10 times stronger than ceramic magnets, for instance, you could substitute a lot smaller neodymium magnet for a ceramic magnet and still produce the same pull-force.

Neodymium, iron, and boron are the main ingredients in the alloy used to create neodymium magnets. The precise composition can change depending on the required strength and the application of the magnet. A neodymium magnet is primarily produced in two ways: sintered and bonded.

Sintered neodymium magnet

The alloy components are heated in a furnace, cast into moulds, and chilled to form ingots, which are then ground into a fine powder and pressed into moulds to create sintered neodymium magnets.

Bonded neodymium magnet

Neodymium alloy powder and a polymer binder are combined to create bonded neodymium magnets. In order to create more complicated forms and magnetization powders than are generally available in sintered magnets, the components are pressed or extruded.

Neodymium fishing magnets

Neodymium magnets are the best magnets for magnet fishing – the strongest and most resilient magnets on the market right now. Even smaller targets can be pulled up with these types of fishing magnets. They were primarily made to lift bulky metallic things.

Magnetic metals

Magnets will securely attract ferromagnetic metals. Ferromagnetic metals include iron, cobalt, steel, nickel, manganese, gadolinium, and lodestone.  Some metals, such as iron, are considered to as magnetically soft because, when a strong magnetic field is placed near them, they temporarily become powerful magnets, but when the magnet is withdrawn, they revert to their original state. Other metals, including rare-earth metals like samarium and neodymium and iron alloys, retain the majority of their magnetism even when they are not in a magnetic field. For this reason, they are referred to as magnetically hard metals and produce good permanent magnets.

Stainless steel is one metal that frequently raises questions about whether or not it is magnetic. There are various different varieties of stainless steels, with ferritic and austenitic being the two primary types. Stainless steels are iron-based alloys with good corrosion resistance.

Due to the distinct atomic configurations between ferritic and austenitic stainless steels, ferritic stainless steels are typically magnetic while austenitic stainless steels are not. Due to the significant amount of iron present and to its basic composition, ferritic stainless steel is magnetic. However, adding nickel during production results in austenitic stainless steel, which is not magnetic.

Because they are weak metals, several metals, including aluminium, copper, brass, lead, gold, and silver, do not draw magnets when they are in their native states. But these metals can be given characteristics like iron and steel to make them magnetic. As an illustration, adding a tiny amount of iron will make silver magnetic.

How do you know how strong a magnet is?

A magnet’s grade is a reliable indicator of its power. Higher numbers often denote a stronger magnet. The Maximum Energy Product of the Magnet Material, which is stated in MGOe, is an actual material attribute that gave rise to the number (Mega Gauss Oersteds). It stands for the BH Curve’s strongest point on the magnet’s demagnetization curve. The grade or N number of a magnet affects the pull force it produces. You can roughly double the draw force by doubling the N number.

Depending on how you define strength The draw force and the strength of the magnetic field are two often used indicators of a magnet’s power.

The amount of force required to pull a magnet away from anything, such as a steel surface or another magnet, is known as the pull force. The exact method used to test the magnet can have a significant impact on the strength that is determined.

The direction and strength of the magnetic field at a certain location close to the magnet are measured as the magnetic field strength. It is measured in Gauss or Tesla, where 1 Tesla is equal to 10,000 Gauss. It depends on the magnet’s size, shape, and quality, the location of the measurement, and whether any additional magnets or ferromagnetic materials are present close by.

What affects the life of a magnet?

Your magnet shouldn’t lose more than 1% of its magnetic strength over the period of 100 years if it is installed and cared for properly. Your magnet may weaken for a variety of reasons, such as:

Temperature – A magnet may become less powerful if heat is applied above the maximum amount recommended for the magnet material in your separator. Conventional rare earth material can withstand temperatures up to 80°C, but standard ceramic material can withstand temperatures up to 200°C. Your system might have used one of the materials that can sustain higher temperatures. Consult the manufacturer if you’re unclear of the system’s maximum working temperature.

Wear and tear – Sharp impacts caused by physical abuse or handling might weaken the magnet and cause impact damage. Because the magnet material in your separator is brittle, these impacts could lead to fractures, which would weaken the material.

Liquid – Moisture may infiltrate inside your magnet housing if the integrity of the housing is compromised. As a result, the magnet’s material may oxidise, thereby diminishing the magnetic field. If the housing is harmed, the magnet should also be replaced for hygiene reasons.

Things you can fish with a magnet

Some rocks that contain iron ore may also attract to your magnet, despite the fact that the majority of these materials are man-made. What you’re likely to find depends on where you fish. Fishing beneath a railroad bridge, for example, might turn up several railroad spikes. While fishing next to a busy road, you could come across objects like lug nuts. Instead of looking for unusual fish, many individuals engage in magnet fishing as a way to spend time on the lake and help the environment. They like the idea of discovering something mysterious that is out of sight.

Wherever you go magnet fishing, there might be some special safety concerns around. For instance, due to unexploded WWII explosives, you must take extreme precautions when magnet fishing in Europe. In various parts of Europe, unexploded shells or grenades are often found; one magnet fisher discovered 19 hand grenades on a single magnet fishing excursion.  Though the risk of getting cut on slick, sharp metal outweighs that of unearthing a live bomb during magnet fishing. When drawing the rope back in, put on gloves to protect your hands.  Anything that has been submerged for an extended period of time is likely covered in algae or other aquatic plants, making it simple to drop or handle improperly. Gloves can aid in traction and help you keep your object from falling into the water.

Magnets must also be used carefully. Because of how strong the magnets used in magnet fishing are, it’s easy to get your fingers caught between them and the thing they’re pulled to. Since styrofoam coolers have firm walls that keep objects apart and prevent them from sticking to your car or boat and scratching the paint, they are typically used by magnet fishers to transport their magnets.

Be prepared when fishing with magnets

Magnetic fishing kit for treasure hunting

The only tools needed to start out with magnet fishing are a magnet, an eyebolt, and some rope. For handling your discoveries, we do advise a set of water- and cut-resistant gloves.

Tangled ropes

To pull your magnet out of the water while magnet fishing, you need at least one rope. To keep track of your magnet, you may occasionally need to use more than one rope, particularly in deep water. As a result, the ropes can easily entangle themselves around one another, creating serious problems that could be disastrous for your magnet fishing. When fishing from a bridge, for example, these ropes can entangle in a larger amount of your magnet, putting you at risk of following the attraction down the river bank. These ropes can take some time to untie because you need to enter the water to loosen the knot.  To prevent these issues in practise, choose a high-quality rope that won’t tangle easily.

The strongest rope to use when fishing with magnets

The ideal fishing rope for magnets is a double-braided rope that can lift up to 1000 kg.  One of the key components of magnet fishing is the rope or line. The magnet fishing line needs to be strong enough to haul even large metals, and it shouldn’t snap when it becomes tangled. You must ensure that you get an excellent magnet fishing rope in the same way that you would a high-quality fishing magnet. You can attach a rope to your magnet and use it as a fishing line. A magnet fishing line with a strong drawing force and a length of between 20 and 30 metres is required if you wish to pull metallic things out of the water.

The majority of magnet fishers often simply think about getting the best magnet for their use. The rope is the second-most crucial piece of gear that might affect magnet fishing success. If you don’t get a sturdy, non-elastic double-braided rope, there is a significant possibility that you may drop your magnet in the water. Due to contact with edges or sharp things, a cheap or elastic rope line will not be able to hold the magnet securely and may even break. The magnet could also go loose in the water.

Which knot is better for magnet fishing depends on the user. Palomar knots are the most popular knots you’ll see people use. The best knots for magnet fishing are generally thought to be three more knots. Due to their strength, the double-figure eight knot, uni knot, and anchor hitch knot are widely used by magnet fishermen.

Big finds recorded in fishing with magnets


Although it may come as a surprise, other magnet fishermen have discovered firearms more frequently than you may imagine. Although not as typical as the things described earlier. Weapons are occasionally discovered in ponds, rivers, and lakes. Typically, a 200kg magnet is sufficient. A firearm should always be handled as though it were loaded. When using any type of gun, it is best to follow gun safety procedures. If you’re fortunate, you might come to find a weapon from a former conflict, like World War 2. When visiting the sites of historic battles, it frequently occurs.


Additionally, cannonballs have been retrieved. It’s unlikely that you’ll find a cannonball unless the water you’re exploring was used in a previous campaign. But if you do find some historical artifacts, you’ll need a powerful magnet to remove them. A cannonball may weigh up to 20 kg. To get one of them out of the water, bring a 600 kg magnet and a sturdy rope with you.


Grenades are by far the most dangerous weapon you can use in water. particularly the grenades that still had their pins connected. When handling grenades, you must exercise tremendous caution. Or, for that matter, any other kind of bomb. These are typically found in former battlegrounds, but they have also been discovered in open areas. This is a good moment to mention contacting the police when you locate guns. They’ll be proficient with both guns and grenades. Be safe and leave these discoveries in the hands of experts.


Although you won’t discover pure silver or gold, you will discover the steel or iron used to make the clasps on bracelets and necklaces that will allow you to retrieve your treasure. Alternately, anything other than pure gold and silver will cling to a magnet as well. For instance, 58.3% of 14k gold is gold, with the remaining “filler” metal making up the remaining weight. This implies that you will be able to reel in a gold necklace or bracelet.

Where can you go fishing with a magnet?

Waterways next to busy pedestrian areas, such as fishing piers, docks, and locations close to bridges, are popular places to go fishing. Most of the material removed from the river is sold to nearby junkyards. Most communities set up bulk trash drop-off places to receive scrap and other garbage; for larger items, numerous recycling facilities and garbage dumps may be employed. Residents of the magnet fishing community place a high value on tidying up after themselves and refraining from leaving trash along the riverbanks. Fun and water stewardship are the two main aims of magnet fishing.

If you have any questions about whether fishing is allowed in a particular location or in regard to anything you pick up, it is always a good idea to check with the local council. Many councils might be pleased with this because it would keep the rivers clean.

Where you can’t go fishing with a magnet

Magnet fishing has become very well-known and popular in recent years. Due to the fact that this sport is still relatively new, there are still some general rules that people should abide by when participating in it. Official magnet fishing regulation has not yet been developed.
As more people engage in the activity, a small percentage will put both themselves and others in danger. Don’t, for example, bring up a World War II grenade you find while magnet fishing without alerting the relevant authorities.

Different types of magnet for fishing

Cube neodymium magnet

A highly common and useful variety of neodymium magnet is the cube magnet. They are cuboids in terms of geometry, having the same length, breadth, and height. The north and south poles of all cube magnets are located on two different faces. You can use a second similar magnet and cautiously test adhesion and repulsion on each of the cube’s distinct sides to find the poles.

Disc neodymium magnet

Due to their adaptability and affordable price, disc magnets are the most popular form of magnet used in today’s major markets and sectors. Numerous industrial, technical, commercial, and consumer applications take advantage of their high magnetic strength in compact shapes and circular, wide, flat surfaces with huge magnetic pole regions.

Rectangle neodymium magnet

Very similar to disc fishing magnets only rectangular in shape.

How a neodymium magnet differs from a ceramic magnet

Magnetic fields are produced by magnets. Magnets may draw certain metals from a distance without coming into contact with them thanks to these magnetic fields. Some magnets are created by humans, while others are found in nature. Although there are many different kinds of magnets, ceramic magnets and neodymium magnets are two of the most widely used artificial magnets.

Both ceramic and neodymium magnets are permanent magnets; they are made of materials that, when charged magnetically, keep their magnetism for a long time unless they are broken. However, not all permanent magnets are created equal. Due to the varied metal alloys used in their production, ceramic and rare-earth magnets have differing strengths and resistance.

A magnet’s magnetic field strength is measured using the maximum energy product, or BHmax, which is expressed in MegaGauss Oersted (MGOe). The strength of the magnet increases with BHmax. NdFeB is the most potent of the rare-earth magnets, with a BHmax of 40, followed by ceramic magnets with a BHmax of 3.5, SmCo with a BHmax of 26, and SmCo.

Ceramic magnets are quite fragile and are prone to breaking. They cannot be utilised in equipment that is subjected to high levels of tension or flexing. When exposed to hot temperatures, they get demagnetized (above 250 degrees Celcius.) They are inappropriate for applications needing strong magnetic fields since they only have a moderate magnetic strength.

The strongest fishing magnet

N52 is one of the highest grades of neodymium, which makes it the strongest rare earth magnet material. As a result, the N52 neodymium magnet is among the strongest magnets on the world. The neodymium magnet grade’s strength, or energy product, is indicated by the number abbreviation, such as N35, N42, N52, or N55.
