For underwater searches, we recommend UMP 75x25 [M10x3] GW F200 GOLD Lina / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~310.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Neodymium magnets are highly effective for retrieving in water environments due to their powerful strength. UMP 75x25 [M10x3] GW F200 GOLD Lina / N42 weighing 900.00 grams with a pulling force of ~310.00 kg is a perfect solution for finding lost treasures.
When choosing a magnetic holder for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the lifting force. UMP 75x25 [M10x3] GW F200 GOLD Lina / N42 has a pulling force of approximately ~310.00 kg, making it a powerful tool for retrieving heavier items. Remember that the full power is achieved with the top attachment, while the side attachment offers only 10%-25% of that power.
The sliding force of a magnetic holder is typically lower than the adhesive 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 Lina / N42 with a lifting capacity of ~310.00 kg, full capabilities are achieved with the upper holder, while the side holder offers only 10%-25% of the declared force.
he attraction force was measured under laboratory conditions, using a smooth S235 low-carbon steel plate with a thickness of 10 mm, with the application of pulling force in a vertical manner. In a situation where the sliding occurs, the magnet's lifting capacity can be 5 times lower! Any gap between the magnet and the plate can result in a reduction in the lifting force.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

  • They do not lose their strength (of the magnet). 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 extremely high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which expands the range of their possible uses.
  • Key role in advanced technologically fields – are used in hard drives, electric drive mechanisms, medical devices or very highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Possible danger associated with microscopic parts of magnets are risky, if swallowed, which is crucial in the context of children's health. Additionally, miniscule components of these magnets are able to be problematic in medical diagnosis when they are in the body.

Notes with Neodymium Magnets

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they 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.

  Neodymium magnets should not be in the vicinity children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Do not bring neodymium magnets close to GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

The magnet is coated with nickel - be careful if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including 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.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can shock you at first.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

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

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
