What Is Magnet Fishing?

This question is pretty common in curious people, they ask what is magnet fishing.

the answer to this question is quite simple.

Did you ever see any metal detector? Or did you notice how they dig metals from the land through a signal? Magnet fishing is similar to this process but instead of finding metal in the land, people find it in the water using strong magnets.

Now, the whole planet is covered with big giant lakes and rivers.

Did you ever imagine, what could be there under the water? These are the witnesses of history and they're right there from a long time ago.

So, there are chances that you'll find out some precious things or historic metals that nobody knows about.

What you need to do is just grab your rope and magnet and boom! You're a magnet fisher.

This hobby is pretty interesting and you can do it with a little cost.

Besides, there is a chance to do a little adventure too! You just need to feel the thrill of magnet fishing because you don't know what you're going to find out.

Maybe you can get something precious that you can't even think of.

How to Go Fishing With Magnets

Magnet fishing is more like going treasure hunting in the water than it is like actual fishing.

In other words, you won’t catch any fish with this method, unless they are made completely of iron or some other strongly magnetic material.

Some treasure hunters throw magnets in lakes and other waterways to attract magnetic metals and pull them up.

The hope is that something valuable will surface, but often miscellaneous items like bottle caps and keys are found as well.

In fact, strong lifting magnets called magnet retrieval tools are specially designed to retrieve items that are lost at the bottom of bodies of water.

However, if you simply wanted to try out magnet fishing and are not looking to retrieve larger, heavier items from the water, you can easily create your own magnet fishing tool.

Magnet Fishing: The Best Magnets for Magnet Fishing

Have you ever wondered what treasures might be buried in your backyard, the beach, or even at the bottom of lakes? While metal detectors are commonly used to look for any objects hidden in the ground, magnets alone can be used to look for metal objects underwater.

If you’ve ever considered trying out this hobby, you would quickly realize some magnets will work better than others due to various reasons.

What are the best magnets for magnet fishing? The best magnet for magnet fishing is a neodymium magnet.

Neodymium magnets are made from rare-earth material metals, which are considered to be some of the strongest metals on earth.

Neodymium magnets vary in type and force, but a common magnet of this kind is the neodymium N52 magnet.

This magnet weighs just under 2 lbs, yet it is capable of producing a pull force of 500 lbs.

It is very important to note that one should never attempt to put two neodymium magnets together, otherwise the magnets will shatter.

Neodymium Magnet

The neodymium magnet is the most widely used type of rare-earth metal magnet and is also a type of permanent magnet made from an alloy of iron and neodymium.

Neodymium magnets are the strongest types of magnets in commercial use and are divided into two subcategories due to different manufacturing processes.

Neodymium is a metal that is categorized as ferromagnetic.

Ferromagnetic metals can be magnetized to become a metal, but in pure form, its magnetism only appears at very low temperatures.

However, when combined with iron, the magnetism reappears at temperatures well above room temperature.

There are two principal manufacturing methods: classic powder metallurgy or sintering process and rapid solidification for bonding.

Sintered neodymium magnets are manufactured by melting the raw materials in a furnace and then cast into a mold for cooling.

This process forms ingots which are then milled into a powder.

The powder is then sintered into blocks that are then reheated, surface treated and magnetized.

Bonded neodymium magnets are manufactured by spinning and melting a thin ribbon of the alloy.

The ribbon is then pulverized, mixed with a polymer, and then injected into bonded magnets.

Factors Determining Neodymium Strength:

Has large magnetic dipole moment

Alternating layers of iron and boron atoms

Neodymium Properties

Remanence- measures the strength of the magnetic field

Coercivity- material’s resistance to becoming demagnetized

Energy product- density of the energy

Curie temperature- the temperature at which the metal loses its magnetism

Neodymium magnets are graded based upon their maximum energy product which is the stored energy in the magnet and relates to its magnetic field.

The maximum energy product is typically measured in megagauss-oersteds which is a unit related to flux density and field strength.

Given that maximum energy is related to flux density, or magnetic flux, a higher value of the energy product indicates a stronger magnet.

Values typically range from 28 to 52.

Any letters following the number values indicate maximum operating temperatures.

As briefly mentioned above, all magnets have several properties that allow users to determine which magnet will work best for their specific purpose.

Neodymium magnets have higher remanence, higher coercivity, higher energy product, yet much lower curie temperatures than other types of magnets.

Some neodymium magnets have been developed using alloys that contain terbium and dysprosium, which raise the curie temperature substantially.

Despite having better properties than all other metals, sintered neodymium tends to be vulnerable to corrosion and causes deterioration.

Deterioration usually results in the magnet crumbling into small magnetic particles.

This problem can be addressed by adding a protective coating to prevent exposure to the atmosphere.

Standard coating methods include nickel plating or two-layered copper-nickel plating.

Polymer coatings are also performed.

Different Neodymium Magnets for Fishing

Neodymium Magnets:

575 LBS Brute Magnetics Round Neodymium Magnet

880 LBS Round Neodymium Fishing Magnet

Uolor Double Side Round Neodymium Fishing Magnets

Wukong 837 LBS Super Powerful N52 Round Neodymium Magnet

As mentioned above, there are different types and different ways to manufacture neodymium magnets which results in variations of all the properties.

For example, the brute magnets listed above can support a force of up to 1,200 lbs, while the Wukong typically supports a pulling force of up to 400 lbs.

The Brute magnetic round neodymium magnet is the best magnet for magnet fishing available in the market.

It contains a pulling force of up to 1,200 lbs and averages at about 600 lbs.

Most of these magnets contain a countersunk hole for ease of use and is also coated in nickel to prevent corrosion.

The second best magnet for magnet fishing is the Uolor double side round neodymium fishing magnet and it has a pulling force of up to 660 lbs.

Besides magnet fishing, this magnet can also be used for hanging and lifting objects in the home.

The magnet also contains coating and an eye bolt screw instead of a countersunk hole.

The third best option for magnet fishing is the Wukong super powerful N52 round neodymium magnet because it has the best type of coating in the market.

It contains a triple layer coat that not only prevents corrosion but also cracking or chipping.

Therefore, it is very durable and lasts a long time.

When deciding between which neodymium magnet to choose, it is important to not only be aware of the pulling force, but it is also important to understand the coating features.

Triple later coated magnets are usually the best.

It is also important to buy a magnet that has a countersunk hole which includes an eyebolt, as the hole is essential to fishing.

Other Magnets for Magnet Fishing

Other magnets for magnet fishing:

Ferrite or ceramic magnets

Mounting Magnets

Before fully settling on neodymium magnets, it is important to realize that yes, there are other magnets which can be used.

Other types of magnets that can be used instead of a neodymium one is a ferrite magnet or a mounting magnet.

Ferrite magnets are the same material as the magnets used on your fridge and are typically a lot cheaper than neodymium magnets and have a bigger diameter that covers more area.

However, it is also noticeably weaker than neodymium magnets and cracks much more often and easier.

Mounting magnets that have a large steel component to them have the ability to life objects underwater.

Many mounting magnets are coated in nickel and have an eye hook that makes them convenient for attaching a rope or cable.

Problems with mounting magnets include their attraction and waterproof capabilities.

The magnet to magnet attraction is not very strong and if they line up with one another, they will repel.

When mounting magnets are not coated, they become very affected by moisture and so it is important for them to be coated.Neodymium Magnet

Related Questions

Are there any hazards to using Neodymium magnets?

Given that these magnets exert greater forces than other metals, a neodymium magnet that is larger than a few cubic centimeters is strong enough to cause harm to body parts that are between two of these magnets.

The stronger magnetic properties may also cause damage to electronic devices as they can erase magnetic media.

Why do you need such a strong magnet for fishing rather than a less strong and less hazardous one?

You may use a magnet that has less force;

however, this will encounter several obstacles that a magnet with little force cannot necessarily overcome.

For example, you will need to achieve flat contact with the object and this may be nearly impossible due to debris accumulation or the object itself simply not being flat.

What is the best rope for magnet fishing?

Along with a strong magnet, one will need a strong rope to go with it.

It is recommended that one buys a rope that is at least 50 ft long for shallow water and 100 ft for deeper depths.

Nylon paracord would be the best rope because it has good strength, durability, elasticity, and is able to hold a knot very well.

Magnet Fishing – Brute Magnetics

Brute Magnetics designs the best and most effective fishing magnets available.

Check out our wide range of pull strengths and sizes for every skill level.

From our 242lb pull to our new cone-shaped magnet, designed to reduce snags on underwater obstacles, we are sure to offer a fishing magnet for every skill level and need.

Magnet fishing is a slimy new hobby where people pull guns, bikes, and weird stuff out of Milwaukee-area rivers, lakes, and lagoons Magnet fishing involves tossing powerful magnets attached to ropes into a body of water and then bringing up whatever metal the magnet latches onto.

big Magnet Fishing With Neodymium Magnets

The best magnet to use for magnet fishing is a neodymium magnet as their relatively compact size can have a huge pull force. Neodymium magnets are rare-earth magnets and are considered to be one of the strongest magnets available.

Best Rope For Magnet Fishing

In addition to a strong magnet, you will need a good rope as your line.

We recommend getting a rope that is at least 50ft in length which would be long enough for shallow water and for fishing in most places.

If you know for sure that where you want to fish is very deep, or you want to be able to cast your line far from the water’s edge, then you can use a 100ft rope.

When fishing from bridges, then definitely use a 100ft rope.

We highly recommend using a good nylon paracord because of its strength, durability, elasticity, high abrasion resistance, and its ability to hold a knot very well;

all these are important given the conditions that you may be fishing in where the water could be murky and the magnet becomes snagged on to something which would take some strong yanking of the rope to un-snag it.

Its elasticity gives it slack, and since the paracord rope is light and thin, the pulling feedback you get when feeling the rope is a lot more sensitive;

you will know when the magnet has caught something.

Be aware that not all paracords are equal as there are different grades of strength depending on how it’s made.

Below is a nylon paracord, and it’s 50 feet in length.

This one is 4mm, type 3, and has 7 braided core yarns that enable it to have a minimum strength of 550lbs making it a perfect complement to the 500lbs magnet.

Magnet Fishing Supplies And Other Equipment

Like any outdoor activity, make sure you take along with you suitable gear to make the most of the experience.

At a minimum, bring a bucket to carry your finds, a brush to get rid of debris, and wear tough gloves to avoid injury when pulling the rope, and handling sharp and rusted metal.

Bring along a small plastic container for storing small items like fishing hooks and lures, nails, and other metal bits.

You can add a grappling hook to your gear which will become handy when retrieving heavy items.

Look after yourself by wearing a hat, sunglasses, and sunblock.

Wearing an insect repellent is very important as mosquitoes breed and inhabit water areas and their surroundings.

You can choose to wear waterproof waders and gumboots depending on the area, such as swamps and wetlands.

Strong Knots To Use For Magnet Fishing

The best knot to use for magnet fishing is one where it tightens on itself, providing a secure hold on the magnet.

Also, the knot needs to be one that is able to bear heavyweight.

If you are a fish angler and have a favorite knot, then try using it for your magnet.

What you need for magnet fishing

The large magnet I have is similar to this magnet

This one is able to lift approximately 110 kg / 242 lbs and weighs 270 grams.

​The best rope for magnet fishing

Depending on the magnet you have you need some rope.

First time I was fishing with small magnets I used a fishing line that had a tensile / breaking strength of 6 kg.

But if you have a 110 kg strong magnet, a fishing line is useless in the fight of a heavy object, unless it is a really strong line!!!

The white rope you can see in the picture is just a normal clothesline.

and up to this day, I haven't caught anything which caused it to break.

When I go magnet fishing, I use that rope off the weakest magnet I have, which can carry 55 kg / 110 lbs

The black and orange rope you see is Paracord.

It is a nylon rope used for parachuting. It has a minimum tensile / breaking strength of 550 lbs ~ 250 kg.

It has a core of 7 strands which makes it extremely strong and durable.

I bought 2 x 100ft.

As you can see I have divided the orange rope into 2 x 50 ft because I often fish in shallow waters.

The colors don't matter at all, but i think the orange rope is easier to find if it breaks at you have to dive into the water to retrieve your magnet.

1050 lb 3mm braided

This braided Honeywell Spectra line has a tensile strength of more than a 1000 lb, almost no stretch, and is UV resistant.

It is actually designed for spearguns so it is made for water and is cut and abrasion-resistant as well.

850 lb paracord

This Paracord is 300 lb stronger than the normal Paracord and is made by a US government certified contractor.

Paracord has a low weight compared to its high strength.

At the same time, the rope cannot rot, which means it is perfect for use in water.

15 KN Climbing rope

This very strong climbing rope is designed to hold people up to 300kg 660lbs and has a tensile strength of 15KN which is equal to more than 3 million pounds.

The rope is thicker than the other two, and you will, therefore, have a better grip on your rope when pulling up heavy treasures.
