Complete Guide To Neodymium Fishing Magnet

What are Neodymium Magnets?

Neodymium magnets are a type of rare earth magnet that is incredibly strong.

They were first discovered in 1982 by General Motors and Sumitomo Special Metals. Neodymium magnets are up to 1.4 times stronger than the previous strongest type of permanent magnet, made from an alloy of samarium and cobalt.

A neodymium magnet is actually an alloy of neodymium, iron, and boron that forms a crystalline structure with formula Nd2Fe14B. Neodymium magnets are extremely strong because they have a high saturation magnetization (can be highly magnetized) and resist demagnetization.

Neodymium – Rare Earth Metal

The strength of a neodymium magnet is measured in Mega Gauss Oersteds (MGOe). The higher the MGOe, the stronger the magnetic field. The highest grade of neodymium magnet has an MGOe of 54.

It is important to note that the strength of a magnet decreases with temperature. For this reason, neodymium magnets are often used in combination with other materials, such as aluminum or copper, to create a more stable magnetic field.

What Kind of Magnets are used for Magnet Fishing?

Neodymium magnets are the strongest type of permanent magnet, they are often used for magnet fishing. When fishing with a magnet, the goal is to attract metallic objects from underwater and pull them to the surface. Neodymium magnets are ideal for this purpose because of their high magnetic strength and resistance to corrosion.

What is the Strongest Neodymium Magnet?

The strongest neodymium magnet is grade N54. The strength of the grade is given by the Mega Gauss Oersteds (MGOe) measurement for the magnet – N54 has 54 Mega Gauss Oersteds and N35 has 35 Mega Gauss Oersteds.

The pull force of the different grades depends on the size and shape of the magnet.

The N54 grade neodymium magnet is about 55% stronger than N32 grade. Neodymium magnets are strong because they are made from an alloy of rare earth metals, including iron, cobalt, and boron.

Neodymium magnets – Grade and Strength

N54 magnets are incredibly strong and often used in applications where a powerful magnetic field is required, such as in electrical motors and generators. While N54 magnets are the strongest type of neodymium magnet, they are also the most expensive and are not readily available. For this reason, you can find N50-N35 neodymium magnets used for magnet fishing.

To prevent corrosion, the N54 and N52 magnets are coated with a nickel-copper-nickel layer.

These magnets can be manufactured in various shapes and sizes. The strength of the magnet will depend on the grade, size and thickness of the neodymium magnet.

What Are The Different Types of Neodymium Magnets You Can Use For Magnet Fishing?

Single-sided Neodymium Magnets

Single-sided neodymium magnets are incredibly powerful for their size and are perfect for magnet fishing. These disc-shaped magnets have a north and south pole on one side, with the opposite side being a flat, smooth surface. The rare earth element neodymium generates a powerful magnetic force.

Single-sided Neodymium Magnet

This concentrated force allows the magnet to pull objects from a considerable distance away, making it ideal for magnet fishing. The smooth surface also makes it easy to attach a rope or chain, meaning that you can fish for objects that are hidden underwater. Single-sided neodymium magnets are also typically smaller and lighter than their double-sided counterparts, making them easier to carry and transport. When shopping for a single-sided neodymium magnet, be sure to choose one rated for the appropriate weight and strength level.


  • A single-sided neodymium magnet for magnet fishing. First, they’re extremely powerful, so they can attract even the heaviest objects.
  • Second, they’re small and lightweight, making them easy to transport and manipulate. And third, they have a smooth, rounded shape that helps reduce drag when pulled through the water.


  • However, there are some drawbacks to using this type of magnet. One downside is that single-sided neodymium magnets can be difficult to remove from the water. This can be a problem if you are trying to fish in a large body of water, as it can be hard to retrieve the magnet once it has sunk to the bottom.
  • Single-sided neodymium magnets can also be dangerous, as they can easily break or shatter if they hit a hard surface. For this reason, it is important to be cautious when handling these magnets.

Double-sided Neodymium Magnets

Double-sided neodymium magnets are ideal for magnet fishing because of their stronghold and versatile design. These magnets have two magnetic poles on opposite sides, allowing them to cling to ferrous metal surfaces with a much tighter grip than other types of magnets.

Double-sided Neodymium Magnet

This makes them perfect for fishing heavy objects out of difficult-to-reach places, such as the bottom of a river or lake. Additionally, the double-sided design means that these magnets can be used with a wide variety of rigging setups. Whether you’re looking to fish for lost keys or treasure, Double Sided neodymium magnets are an essential tool for any magnet hobbyist.

  • A double-sided magnet will have twice the pulling power of a single-sided magnet of the same size. This means that you’ll be able to pull up heavier objects from the bottom of the body of water you’re fishing in.
  • A double-sided magnet is less likely to get stuck on debris than a single-sided one, as the magnetic force is distributed evenly over both sides.
  • A double-sided magnet is less likely to lose its grip on an object than a single-sided magnet, as there’s always another side that can make contact.


  • One downside is that they can be difficult to remove once they’ve been attached to something. This can be frustrating if you’re trying to fish something out of a lake or pond, as you may need to use a lot of force to break the bond between the magnet and the object.
  • Double-sided neodymium magnets can be dangerous if not used correctly. If the magnet flips over while it’s attached to something, it could potentially fly off and hit someone.

Clamp Neodymium Magnets

Clamp neodymium magnets are fishing magnets designed to be clamped onto a rod or long stick. They are encased in a durable plastic shell. These magnets are incredibly powerful and can easily pick up objects that weigh several pounds. They are also very compact, making them easy to transport and store.

Clamp Neodymium Magnet

When shopping for Clamp neodymium magnets, it is important to look for ones that have a high pulling force. This will ensure that the magnet is strong enough to attract and hold onto the desired object. It is also important to choose a magnet that is the right size for the application. For example, a smaller magnet should be used if the goal is to retrieve a small object from a water body. On the other hand, if the goal is to retrieve a large object, such as a car bumper, then a larger magnet would be necessary.


  • Clamp magnets are made up of a bunch of smaller magnets that are fused, resulting in a stronger overall magnet. This makes them ideal for fishing heavier objects out of the water.


  • Clamp magnets can be more difficult to handle due to their size and weight.
  • Due to the materials that are used to make them, they can be more expensive than other types of magnets.

360 Neodymium Magnets

Three hundred and sixty neodymium magnets are one of the most popular types of magnets used in magnet fishing. These magnets are powerful and have a stronghold, making them perfect for retrieving heavy objects from the bottom of a body of water. As the name suggests, these magnets have a 360-degree magnetism, allowing them to be used in various ways.

Regardless of their use, 360 neodymium fishing magnets are incredibly powerful and can hold up to 200 pounds of weight. In addition, they are also very durable and resistant to corrosion. They make for a good choice for people who want to retrieve heavy objects or those who are looking for a magnet to last for years.


  • One of the main advantages is that it can be used to fish for objects in deeper water.
  • It has a stronger magnetic force, so it can be used to fish for larger objects.


  • The most obvious is that it can be more dangerous to use since the magnetic force is so strong. If it isn’t handled properly, it could cause serious injury.
  • There is also the risk that it could damage any electronic equipment that it comes into contact with. Therefore, it is important to weigh the pros and cons before choosing to use a 360 neodymium magnet for magnet fishing.

Getting the Right Magnet Fishing Setup

Magnet fishing is a great way to find hidden metal treasures, but it will be hard for you to retrieve anything if you do not have the right setup. First, you’ll need a strong magnet. Neo magnets are the strongest permanent magnet type, so they’re a good choice for magnet fishing.

Why you Should Buy a Neodymium Magnet for Magnet Fishing?

Neodymium magnets have incredibly strong magnetic fields, they can offer many benefits over traditional ceramic or ferrite magnets. For example, they are much smaller and lighter for a given level of magnetic strength, making them ideal for use in magnet fishing.

They also have a higher coercive force, meaning they can resist being demagnetized by external magnetic fields or if you drop them a few times. While magnet fishing your magnet will be in water most of the time and sometimes mud so the protective nickel cooper coating on you neodymium magnet will be very helpful. This helps with the protecting your magnet from rusting. This is a big deal since rust actually affects the power of you magnet over a period of time. You will have to clean you magnet after every trip so even if it is pricier always buy a neodymium magnet which has a protective coat on it.

Finally, neodymium magnets are very affordable compared to other types of permanent magnets.

If you are a beginner and are looking to start in magnet fishing, you can choose a cheap single sided neodymium magnet. If you are looking to go big and pull some serious weight out of the water the 360 neodymium magnets are the strongest and the most expensive.

Neodymium Magnet Fishing Kit

A neodymium magnet fishing kit is a set of tools that can be used to fish for metal objects in water. The Neodymium magnet fishing kits usually contain everything you need to go for magnet fishing. The magnet fishing kits come with a neodymium magnet, ropes, gloves, hooks, and a rope or cord so that you can attach the magnet to an object and pull it out of the water. The kit may also include a carrying case so that you can keep the magnets organized and protected. Neodymium magnet fishing kits are available for purchase online and in stores.

Factors to Consider When Choosing a Neodymium Magnet Fishing Kit

Since there are many neodymium magnets available, it is important to select the magnet that will be most suitable for your needs. It is also important to note that the price of the neodymium magnet fishing kit will be affected by several factors, such as the strength of the magnet and the quality and durability of other items that are contained in the kit.

There are a few factors to consider when choosing a neodymium magnet kit for fishing.

Strength of the magnet.

The stronger the magnet, the more weight it can hold. However, too strong of a magnet can be difficult to handle and can cause damage to both the objects being fished and the person holding the magnet. Powerful magnets can also get stuck to objects and can be extremely hard to remove (get unstuck).

Size of the magnet.

A larger magnet will be able to hold more weight, but it will also be more difficult to maneuver.

Coating on the magnet.

A coated magnet will be less likely to rust, but it may not be as strong as an uncoated Magnet.

When choosing a neodymium magnet for magnet fishing, carefully consider all of these factors to ensure that you choose the best possible option for your needs.

Additional items in the Kit and their quality.

Finally, you have to determine the quality of other accompanying items, for example, the size and strength of the rope. This is because even with a strong magnet, you will need rope made of a durable material like nylon or Kevlar and strong enough to support the weight of the magnet and the item/s that are being retrieved.

You’ll also need to determine the length of rope based on where you are magnet fishing – if you are going for deep sea magnet fishing or going to a shallow river or murky lake.

You should also ensure you tie the magnet using the right knotting technique. Since you will pulling the magnet from under the water with a heavy load and this may cause the knot to come lose and you losing your magnet.

You should also consider if you kit has a nice pair gloves since the items you will get magnet fishing are usually rusted iron or steel objects and can serious injury you if handled incorrectly. Good gloves will protect you hands and palms.

Finally, you’ll need something to use as a grapple, like a grappling hook or folding anchor.

If your kit has all these additional things you are all set. Simply tie the magnet to one end of the rope and you’re ready to start magnet fishing!
