Magnets for Effective Metal Fishing

Effective Metal Fishing

Have you ever wondered whether there are buried treasures on your property or in areas near the beach? Well, you’re not alone! People are searching for metals and gold with the help of metal detectors in rivers, lakes, and mines. While the metal detectors are often used for coins and gold bars in the ground, the magnets can be quite effective for those treasures that are submerged underwater. If you want to try this hobby, it’s best to know and realize that every magnet is quite different with effective metal fishing. They were not made equally, and some will work on freshwater while others are better off in seas.

So, what’s the best magnet for these kinds of angling? One of the best is a cone magnet made from neodymium. Neodymium is a rare earth metal that’s considered to be the strongest on earth. Their forces and types may vary, but it’s common for professionals to use a neodymium N52 magnet. This weighs a little under 2 pounds but is quite capable of pulling a 500-pound metal underwater.

It’s essential to know that you should not try putting two neodymium rare-earth metals together. Otherwise, they will break each other apart. Magnets for Effective Metal Fishing-

What to Know about the Neodymium Element?

Neodymium Element

One of the most widely used rare-earth magnets today is neodymium. You can find people using this around the world. This is made from an alloy of neodymium and iron, and it’s a type of permanent magnet. They are the strongest types that are used in many commercial projects, and they can be divided into subcategories during the manufacturing process.

This is a metal categorized as a ferromagnetic one. These are magnetized and created to be metals in their pure forms. However, magnetism is only available at a very low temperature. ( However, when you add iron to the ferromagnets, their abilities for magnetism may reappear above room temperatures.

Two manufacturing methods are used by various companies worldwide: There’s rapid solidification for bonding and the sintering process or classic powder metallurgy. Read more about this kind of metallurgy on this site here

The sintered neodymium lodestone may be made by melting various raw materials into a furnace. They will then be cast in a kind of mold and left to cool. The process will form small ingots that are then milled into fine powders. The powder will then have to be sintered into a block where it will be reheated, magnetized, and surface treated.

Bonded varieties can be manufactured by spinning, and a thin ribbon of the alloy is melted in the process. The ribbons will be pulverized, added with polymer, and injected into the bonded lodestones.

Various Factors in Determining the Strength

  • Crystal structure specific to the material used
  • Current microcrystalline grain alignment
  • If there was a large moment of magnetic dipole
  • Alternate ribbons of boron atoms and iron

Properties to Know


  • The coercivity is the metal’s resistance to becoming demagnetized
  • Energy product means its density
  • Remanence is the measure of the strength of the magnetic fields
  • Curie temperatures are the range of temperature when the metal is going to lose its magnetism

Neodymium is often graded based on its energy product that relates to the overall magnetic field. Maximum energy products are measured through Megagauss-oersted, and this is a unit pertaining to field strength and flux density. ( More about oersted in this link:

Since the maximum energy is related to magnetic flux, the higher value will mean that you’re getting a stronger magnet. The value starts from 28 and ends with 52. When there are letters following these values, they usually indicate the materials’ maximum operating temperature.

As mentioned, neodymium has various properties that allow users to know which will work best for a specific purpose. If you’re going to fish for metals, there are particular energy products, remanence, and coercivity that you should know depending on whether you’re going to the ocean or lakes. 

Varieties to Know About

Plastic Cones

Plastic Cones – If you’re going in a body of water that has plenty of vegetation, then a plastic cone cover may be the ideal choice for you. This is when you can avoid snagging hazards, and these are also excellent choices for beginners. Select a color that you can easily sea underneath clear or shallow waters. The neon colors can do the job well when it comes to visibility.

Metal Cones – Neodymium metal cones are excellent when it comes to snagging useless things and hazards. It has a cover and has a unique shape and exclusive design. Overall, this magnet has a pulling strength of about 375 pounds.

Magnet Kits – The kits are often weatherproof and durable. It includes a carabiner, rope, thread locker, hardshell case, and more. This is something that you can purchase ultimately, where you can choose from various breakaway strengths from 300 pounds to 1200 pounds. 

Some of these materials have been developed as an alloy containing dysprosium and terbium, which substantially raises their curie temperatures.

Aside from having various properties from many metals, sintered neodymium may quickly deteriorate because of its vulnerability to corrosion. The deterioration process usually comes from the crumbling of small magnetic particles, and the problems are generally addressed with an additional coating to avoid further exposure to air.

You might want to check out the Brute neodymium materials that are excellent for fishing. They are available in many markets and can have a pulling force of about 1,200 pounds, and the average is 500pounds as well. Most of them may contain countersunk holes to be used easily, and the nickel usually prevents corrosion.

The second-best ones for fishing are the double side round neodymium magnets that have a pulling force of more than 600 pounds. Aside from fishing, they can also be used at home to lift and hang objects. They contain eye bolt screws and coatings that are comparable to that of a countersunk hole.

When you’re in the market to choose the best fishing magnets for effective metal fishing, you need to be aware of their pulling force and understand their coating features better. The triple-layered ones are usually some of the best choices that you have.
