For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42, which is very powerful and has an impressive magnetic pulling force of approximately ~601.00 kg. This model is ideal for retrieving metal objects at the bottom of water bodies.
Neodymium magnets are ideal for searching in water due to their strong attraction capability. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 weighing 1800.00 grams with a pulling force of ~601.00 kg is a great choice for finding metallic findings.
When choosing a magnet for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 has a pulling force of approximately ~601.00 kg, making it a powerful tool for recovering objects with significant mass. Remember that the maximum strength is achieved with the top attachment, while the side attachment offers only 10%-25% of that power.
The sideways force of a magnet is typically lower than the perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 with a lifting capacity of ~601.00 kg, maximum power are achieved with the top attachment, while the side holder offers only one-fourth to one-quarter of the stated power.
he attraction force was measured under test conditions, using a smooth S235 low-carbon steel plate with a thickness of 10 mm, with the application of pulling force in a perpendicular manner. In a situation where the sliding occurs, the magnet's lifting capacity can be 5x times lower! Any gap between the magnet and the plate can result in a reduction in the attraction force.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

  • They do not lose strength over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic sources,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They exhibit very high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Wide application in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical equipment or various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Potential hazard arising from small pieces of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that small elements of these magnets are able to complicate diagnosis after entering the body.

Be Cautious with Neodymium Magnets

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets are noted for being fragile, which can cause them to shatter.

Magnets made of neodymium are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.

  Do not give neodymium magnets to children.

Neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

The magnet coating contains nickel, so be cautious if you have a nickel allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a severe pressure or even a fracture.

So that know how strong neodymium magnets are and why they are so dangerous, read the article - Dangerous powerful neodymium magnets.
