For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 GOLD DUAL / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~601.00 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.
Magnetic holders are efficient for retrieving in water due to their powerful strength. UMP 75x25 [M10x3] GW F200 GOLD DUAL / N42 weighing 1800.00 grams with a pulling force of ~601.00 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 75x25 [M10x3] GW F200 GOLD DUAL / N42 has a pulling force of approximately ~601.00 kg, making it a powerful tool for retrieving objects with significant mass. Remember that the full power 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 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 DUAL / N42 with a pulling force of ~601.00 kg, full capabilities are achieved with the top attachment, while the side holder offers only one-fourth to one-quarter of the declared force.
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 lifting force in a vertical manner. In a situation where the sliding occurs, the magnet's attraction force can be 5 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.

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

  • They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have 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 shape) even at temperatures up to 230°C and above...
  • The ability for precise shaping or customization to specific 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 used in HDD drives, electric motors, medical devices 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 protective case. 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 strength 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,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Possible danger associated with microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. Additionally, miniscule components of these magnets can be problematic in medical diagnosis after entering the body.

Be Cautious with Neodymium Magnets

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Neodymium magnets generate strong magnetic fields that can destroy 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. Remember not to place neodymium magnets close to these 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 magnetic are incredibly fragile, they easily crack as well as can become damaged.

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

  Magnets are not toys, youngest should not play with them.

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

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

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

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

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been found 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.

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 not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
