For exploring rivers and lakes, we recommend UMP 65x45 [M8] GW, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~${capacity} kg. This model is ideal for retrieving metal objects at the bottom of water bodies.
Magnetic holders are highly effective for retrieving in water environments due to their powerful strength. UMP 65x45 [M8] GW weighing ${weight} grams with a pulling force of ~${capacity} kg is a perfect solution for recovering 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 65x45 [M8] GW has a pulling force of approximately ~${capacity} kg, making it a powerful tool for recovering heavier items. Remember that the maximum strength is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sideways force of a magnetic holder is typically lower than the perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 65x45 [M8] GW with a lifting capacity of ~${capacity} kg, maximum power are achieved with the upper holder, while the side attachment offers only 10%-25% of the stated power.
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 pulling force in a vertical 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 attraction force.

Product suggestions

Advantages as well as 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 strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field very well,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
  • Wide application in the industry of new technologies – are utilized in computer drives, electric motors, medical devices and very modern machines.

Disadvantages of neodymium magnets:

  • They can break 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 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
  • Health risk associated with microscopic parts of magnets are risky, in case of ingestion, which is crucial in the aspect of protecting young children. Additionally, miniscule components of these magnets can hinder the diagnostic process in case of swallowing.

Caution with Neodymium Magnets

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

If the joining of neodymium magnets is not under control, then they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them very firmly.

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can lose their magnetic properties 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.

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

Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. 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.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

The magnet is coated with nickel. Therefore, exercise caution 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are especially fragile, resulting in damage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

People with pacemakers are advised to avoid neodymium magnets.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

  Neodymium magnets should not be around youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can surprise you.

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

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
