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.

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.

Table of Comparison – Neodymium Magnet Grades, Their Pull Force (Strength) and Price

Pull Force – The force that's required to draw a magnet straight vertically from a steel surface.

Pull force is measured in pounds. It is also a reliable way of determining the magnet's maximum strength. It tells you the limit of its holding power.

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!
