For underwater searches, we recommend UMP 94x40 [3xM10] GW F550 Silver Black / N52, which is very powerful and has an impressive magnetic pulling force of approximately ~650.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Magnetic holders are efficient for retrieving in water due to their powerful strength. UMP 94x40 [3xM10] GW F550 Silver Black / N52 weighing 2262.00 grams with a pulling force of ~650.00 kg is a perfect solution 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 lifting force. UMP 94x40 [3xM10] GW F550 Silver Black / N52 has a pulling force of approximately ~650.00 kg, making it a effective solution for recovering heavier items. Remember that the full power is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sliding 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 94x40 [3xM10] GW F550 Silver Black / N52 with a lifting capacity of ~650.00 kg, maximum power are achieved with the upper holder, while the side attachment offers only one-fourth to one-quarter 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 vertical manner. In a situation where the sliding occurs, the magnet's attraction force can be five times lower! Any gap between the magnet and the plate can result in a reduction in the lifting force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time - after about 10 years, their power decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
  • They have exceptionally 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...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Significant importance in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical equipment and very highly developed apparatuses.

Disadvantages of neodymium magnets:

  • 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 at the same time increases its overall strength,
  • High temperatures can reduce the power 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,
  • 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,
  • 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
  • Health risk to health from tiny fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting young children. Furthermore, miniscule components of these devices have the potential to hinder the diagnostic process after entering the body.

Exercise Caution with Neodymium Magnets

Neodymium magnets should not be near people with pacemakers.

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 can demagnetize at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

If you have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or a fracture.

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

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

Neodymium magnetic are particularly fragile, which leads to damage.

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. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

The magnet is coated with nickel. Therefore, exercise caution if you have an 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 around youngest 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.

In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
