For underwater searches, we recommend UMP 97x40 [M8+M10] GW F300 Lina / N38, which is very powerful and has an impressive magnetic pulling force of approximately ~380.00 kg. This model is ideal for retrieving metal objects at the bottom of water bodies.
Neodymium magnets are ideal for retrieving in water environments due to their high lifting force. UMP 97x40 [M8+M10] GW F300 Lina / N38 weighing 2200.00 grams with a pulling force of ~380.00 kg is a great choice for recovering lost treasures.
When choosing a magnet for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 97x40 [M8+M10] GW F300 Lina / N38 has a pulling force of approximately ~380.00 kg, making it a powerful tool for recovering 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 97x40 [M8+M10] GW F300 Lina / N38 with a lifting capacity of ~380.00 kg, full capabilities are achieved with the upper holder, while the side attachment offers only 10%-25% of the declared force.
he Lifting force was measured under test conditions, using a smooth S235 low-carbon steel plate with a thickness of 10 mm, with the application of lifting force in a perpendicular manner. In a situation where the force acts parallelly, the magnet's lifting capacity can be 5x times lower! Any gap between the magnet and the plate can cause a reduction in the lifting force.

Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose power over time - after 10 years, their power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • 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,
  • Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which expands the range of their possible uses.
  • Key role in the industry of new technologies – are used in hard drives, electric motors, medical equipment or very modern machines.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile 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 simultaneously increases its overall strength,
  • They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form 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 recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Health risk arising from small pieces of magnets are risky, when accidentally ingested, which is particularly important in the context of child safety. Furthermore, miniscule components of these products are able to hinder the diagnostic process after entering the body.

Caution with Neodymium Magnets

  Neodymium magnets should not be in the vicinity children.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

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

Avoid contact with neodymium magnets if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Avoid bringing neodymium magnets close to a phone or GPS.

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.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

Dust and powder from neodymium magnets are 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 magnetic are highly susceptible to damage, leading to shattering.

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.
