What is a magnet fishing?
Magnet fishing is similar to metal detecting in that it involves utilising powerful magnets called "fishing magnets" to locate metal items in bodies of water. Have you ever wondered what may lie at the bottom of a lake near your home? People who were interested enough to attach a magnet to the end of a rope to find an answer have made some intriguing discoveries - many of them were pleasantly surprised by what they discovered.
Magnet fishing is a fun and economical outdoor sport that anybody can participate in, and it allows outdoor enthusiasts to engage with their surroundings in a unique way. Imagine the joy of not knowing what you'll find next, the delight of retrieving some metal treasure from the water, and the ability to view what's 'below the surface' when you come across an unusual water place where you think something exceptional is hiding.
You'll need a few items for your magnet fishing gear and setup. Magnet fishing, like fish angling, requires a powerful magnet as the hook and sinker, as well as a rope that attaches to the magnet as the line. It's vital to magnet fish in the right places to enhance your chances of discovering metal, and you'll need a lot of patience and curiosity. Magnet fishing, unlike fish angling, yields faster results in capturing anything; you'll immediately learn if there's any metal hiding beneath the surface and will be able to reel it in when you feel the magnet adhere to something.
Magnet fishing necessitates the use of a powerful magnet. It's preferable to obtain the most powerful magnet you can and secure it to a rope. Keep in mind that the magnet's draw power is greatest when the metal item lies completely flat on it. Flat contact is difficult to obtain while magnet fishing since things that have been laying at the bottom of a lake for a long time tend to gather debris, and the metal object itself may not be flat - which is why the strongest magnet is recommended. Remember that larger findings will require a stronger magnet to be hauled out of their long-term resting spot, through the water, and out.

What fishing magnet is best for magnetic fishing?
While metal detectors are frequently used to search for concealed things in the ground, fishing magnets may also be used to search for metal objects underwater.
If you've ever contemplated taking up this activity, you'll quickly discover that some magnets perform better than others for a variety of reasons.
What magnets are the best for magnet fishing? A neodymium magnet is the ideal magnet for magnet fishing. Rare-earth material metals, which are among of the strongest metals on the planet, are used to make neodymium magnets.
Neodymium magnets come in a variety of types and strengths, but the neodymium N52 magnet is one of the most prevalent. This magnet only weighs a little more than 2 pounds, yet it has a 500-pound draw power. It is critical to remember that attempting to combine two neodymium magnets will result in the magnets shattering.
The most common form of rare-earth metal magnet is the neodymium magnet, which is also a sort of permanent magnet manufactured from an alloy of iron and neodymium. Neodymium magnets are the most powerful commercial magnets, and they are separated into two groups due to differing production procedures.
The metal neodymium is classified as ferromagnetic. Ferromagnetic metals can be magnetised to create metals, although their magnetism is only visible at very low temperatures in their pure state. When coupled with iron, however, the magnetic returns at temperatures much higher than room temperature.
The traditional powder metallurgy or sintering technique and fast solidification for bonding are the two main production processes.
Sintered neodymium magnets are made by melting raw materials in a furnace, then casting them into a mould to cool. Ingots are formed, which are subsequently processed into powder. After that, the powder is sintered into blocks, which are warmed, surface treated, and magnetised.
A narrow ribbon of the alloy is spun and melted to create bonded neodymium magnets. The ribbon is then crushed, combined with a polymer, and injected into magnets that have been bound together.
The maximum energy product, which is the stored energy in the magnet and corresponds to its magnetic field, is used to grade neodymium magnets. Megagauss-oersteds, a unit linked to flux density and field strength, are commonly used to quantify the maximal energy product.
Because maximum energy is proportional to flux density, or magnetic flux, a greater energy product implies a more powerful magnet. The average range of values is 28 to 52. Maximum operating temperatures are indicated by any letters after the numerical values.
All magnets have a number of qualities that allow consumers to evaluate which one is ideal for their needs. Neodymium magnets have a stronger remanence, coercivity, and energy product than other types of magnets, although they have far lower curie temperatures.
Some neodymium magnets have been created using alloys including terbium and dysprosium, which significantly boost the curie temperature.
Sintered neodymium, although having superior qualities to all other metals, is prone to corrosion and degradation. When a magnet deteriorates, it generally crumbles into microscopic magnetic fragments. This issue can be solved by applying a protective covering that prevents exposure to the environment.
Nickel plating or two-layered copper nickel plating are common coating processes. Coatings using polymers are also done.
As previously stated, there are several types and methods for producing neodymium magnets, resulting in a wide range of qualities. The brute magnets indicated above, for example, can withstand a drawing force of up to 1,200 lbs, but the Wukong can withstand a pulling force of up to 400 lbs.
The Brute magnetic circular neodymium magnet is the finest magnet available for magnet fishing. It has a maximum pulling force of 1,200 lbs and an average pulling force of 600 lbs. The majority of these magnets have a countersunk hole for convenience of usage and are nickel-plated to prevent corrosion.
The Uolor double side round neodymium fishing magnet is the second best magnet for magnet fishing, with a drawing force of up to 660 lbs. This magnet may be used for hanging and lifting things around the house in addition to magnet fishing. In place of a countersunk hole, the magnet has a coating and an eye bolt screw.
The Wukong super strong N52 round neodymium magnet is the third best option for magnet fishing since it has the greatest type of coating on the market. It has a three-layer coating that inhibits corrosion as well as cracking and chipping. As a result, it is extremely resilient and long-lasting.
When determining which neodymium magnet to buy, it's crucial to consider not only the pulling force, but also the coating properties. The best magnets are generally those with three layers of later coating.
It's also crucial to get a magnet with a countersunk hole and an eyebolt, as the hole is necessary for fishing.
Is magnet fishing legal?
Magnet fishing is growing increasingly popular, and it has received a lot of press in recent years. Because this is a new sport, there are no specific magnet fishing regulations in place yet, but there are certain basic guidelines that individuals should observe when participating in this activity.
As more individuals take up the activity, there will be a few who will endanger themselves and others. Stories of people finding grenades or other dangerous objects can frighten individuals and alarm authorities, prompting them to take action, which generally results in the practise being outlawed outright.
In the United Kingdom, magnet fishing is only lawful if it takes place on private land and with permission. It is not permitted on Canal & River Trust-owned land. Please ask the relevant authorities for permission before attempting magnet fishing anywhere that is private.
What is neodymium?
The chemical element neodymium has the symbol Nd and the atomic number 60. It is the fourth member of the lanthanide family and is classified as a rare-earth metal. It's a silvery, firm, somewhat malleable metal that tarnishes fast when exposed to air and moisture. In the +2, +3 and +4 oxidation states, neodymium reacts fast to form pink, purple/blue, and yellow compounds. It is said to have one of the most complicated spectra of all the elements. Carl Auer von Welsbach, an Austrian scientist who previously discovered praseodymium, discovered neodymium in 1885. It may be found in large amounts in the minerals monazite and bastnäsite.
Neodymium is rarely found in metallic form or unmixed with other lanthanides in nature, therefore it must be purified for common usage. Neodymium is a common element with a wide distribution in the Earth's crust, roughly as prevalent as cobalt, nickel, or copper. China, like many other rare-earth metals, mines the majority of the world's commercial neodymium.
Neodymium compounds were first used commercially as glass dyes in 1927 and are still widely used today. Because to the interaction of the acute light absorption bands of neodymium with ambient light enhanced with the sharp visible emission bands of mercury, trivalent europium, or terbium, the hue of neodymium compounds is frequently a reddish-purple, but vary with the kind of illumination. Lasers emitting infrared with wavelengths between 1047 and 1062 nanometers employ neodymium-doped glasses. These lasers have been employed in high-power applications such as inertial confinement fusion studies. In the Nd:YAG laser, neodymium is combined with a variety of different substrate crystals, including yttrium aluminium garnet.
High-strength neodymium magnets—a sort of strong permanent magnet—are made from neodymium alloys. Low magnet mass (or volume) or strong magnetic fields are required in items such as microphones, professional loudspeakers, in-ear headphones, high-performance hobby DC electric motors, and computer hard drives. In electric motors with a high power-to-weight ratio (e.g., hybrid automobiles) and generators, larger neodymium magnets are employed (e.g., aircraft and wind turbine electric generators).
Neodymium is seldom found in nature as a free element; instead, it is found in ores containing minor quantities of all rare-earth metals, such as monazite and bastnäsite (these are mineral group names, not single mineral names). Neodymium is seldom prominent in these minerals (as it is in lanthanum), with cerium being the most prevalent lanthanide; monazite-(Nd) and kozoite-(Nd) are two exceptions (Nd). China, the United States, Brazil, India, Sri Lanka, and Australia are the primary mining regions. The world's neodymium reserves are believed to be eight million tonnes.
The strongest permanent magnets are neodymium magnets (really an alloy, Nd2Fe14B). A few tens of grammes of neodymium magnet can lift 1,000 times its own weight and snap together with enough power to crush bones. Compared to samarium–cobalt magnets, these magnets are less expensive, lighter, and stronger. However, they are not perfect, as neodymium-based magnets lose their magnetism and corrode at lower temperatures, but samarium–cobalt magnets do not.
Neodymium magnets are used in items like microphones, professional loudspeakers, in-ear headphones, guitar and bass guitar pick-ups, and computer hard drives that need low mass, tiny volume, or high magnetic fields. Neodymium is utilised in hybrid and electric vehicle electric motors, as well as in the electrical generators of several commercial wind turbine designs (only wind turbines with "permanent magnet" generators use neodymium). For example, each Toyota Prius' drive electric motors require one kilogram (2.2 pounds) of neodymium.
Researchers from Radboud University and Uppsala University reported in 2020 that they had discovered "self-induced spin glass" in the atomic structure of neodymium. Individual atoms' structures may be seen, and the north and south poles of the atoms can be resolved. We were able to identify the behaviour in neodymium thanks to this development in high-precision imaging since we were able to detect the exceedingly minute changes in the magnetic structure.

What do you fish for with a magnet?
As you may expect, there are a plethora of items you can capture while magnet fishing. From nuts and bolts to signposts, bicycles, tools, and even the fishing classic – an old boot – everything that contains iron is within your grasp.
A safe is one of the most thrilling items you may find hooked to your magnet. In fact, you'd be shocked how frequently antique safes are discovered in waterways. They're usually empty, having been abandoned after a heist. Every now and again, though, a lucky fisherman comes across a real-life treasure trove.
Then there are the guns, which are the holy grail of magnet fishing. Many firearms have been discovered in rivers and canals, particularly in Europe, which appears to be strewn with WWII weapons. Revolvers are occasionally fully functional, but if you come across a contemporary firearm, you should probably contact the cops — there's a reason someone dumped it in a canal.
Metal may be found in almost any river or pond where humans congregate. Popular destinations include bridges, canals, and piers. There's a strong possibility someone misplaced their keys, dropped their bait knife, or even drove their bike into the river because there's a lot of foot and boat activity. Piers and jetties are also great places to look for vintage fishing lures. Famous historical places may have been robbed by previous treasure seekers, but they're still worth a try. Historic ports and ancient riverbank roadways may also be gold mines. Finally, objects that have washed downstream will clutter river mouths and spillways.
What to know about magnet fishing safety
As you would expect, hauling rusted metal out of a river comes with a number of risks. The most obvious is cutting oneself, therefore wear gloves when searching for larger items. If you haven't had a tetanus booster in a while, it's a good idea to get one now.
Another, far more serious threat to be wary of is unexploded explosives. This is a considerably more widespread problem in Europe, where WWII explosives are still being discovered on a daily basis. Even in the United States, an old grenade may be found in the bottom of a river. If you discover one, carefully drop it back into the water, tie off your rope, and contact the authorities.What are the best magnet fishing finds?
Gas mask from 1944 - During WWII, this was lost in the Battle of Hurtgen Forest in 1944. On February 11, 1944, the 28th Infantry Division advanced. This was one of the war's longest and deadliest battles. This sort of discovery would appeal to a wide range of collectors.
Military dog tags - To a casual magnet fisherman, it's cool, but to a family member, it's priceless. Hopefully, the soldier's belongings were restored to his family. I've heard a number of stories of people discovering dog tags while magnet fishing. If you're having trouble selecting what to do with misplaced dog tags, keep in mind that the soldier's family is almost certain to want them. The Department of Defense can assist you in tracking down the owner's relatives.
Diamond bracelets - Someone discovered that diamonds last a lifetime when magnet fishing in the River Thames. He actually discovered two of these diamond bracelets, as well as a few coins. He'll make a lot of money if he decides to sell these bracelets. Even if the items aren't old, a 1-carat diamond can cost anything from £1500 to £16,000.
Thousands of bullets - It's one thing to catch a few of bullets now and again. However, when you wind up with 3,000 shots from a river, it's incredible. When a 6-year-old girl from Surrey went magnet fishing, this is what happened to her. She was casting from an old bridge beneath a viaduct, and she couldn't stop bringing in bullets. Of course, the bullets' origin wasn't surprising, given that Leah and her parents had been magnet fishing near the Pirbright Army Training Centre. That wasn't the only thing they discovered. They've also discovered safes, cash registers, computers, and bicycles along the route.
The Enigma codebreaker - You'll adore this find if you're a WWII history enthusiast. From the dirt at the bottom of a pond, someone discovered an Enigma codebreaking machine. Breaking the Enigma code was undoubtedly one of the Allies' most significant advantages during WWII, and England was able to do it with the aid of Polish codebreakers. Allied forces were able to know about German positions and plans during their blitzkrieg strikes thanks to the "Ultra" intelligence obtained by cracking the Enigma code.
