For exploring rivers and lakes, we recommend UMP 79x50 [M8] GW, which is very powerful and has an impressive magnetic pulling force of approximately ~340.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Neodymium magnets are highly effective for retrieving in water due to their high lifting force. UMP 79x50 [M8] GW weighing 1.95 grams with a pulling force of ~340.00 kg is a perfect solution for recovering metallic findings.
When choosing a magnetic holder for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the lifting force. UMP 79x50 [M8] GW has a pulling force of approximately ~340.00 kg, making it a powerful tool for recovering 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 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 79x50 [M8] GW with a pulling force of ~340.00 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 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 lifting capacity can be 5 times lower! Any gap between the magnet and the plate can cause a reduction in the lifting force.

Shopping tips

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 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic sources very well,
  • 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,
  • 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...
  • Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Wide application in modern technologies – are utilized in computer drives, electric motors, medical apparatus and very modern machines.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. 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,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • 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
  • Potential hazard arising from small pieces of magnets are risky, when accidentally ingested, which is crucial in the context of child safety. It's also worth noting that tiny parts of these magnets can be problematic in medical diagnosis when they are in the body.

Safety Precautions

  Do not give neodymium magnets to children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that 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.

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

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.

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

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.

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 may crack or crumble with uncontrolled joining to each other. You can't move them to each other. At a distance less than 10 cm you should hold them extremely strongly.

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

Neodymium magnetic are especially delicate, which leads to their breakage.

Magnets made of neodymium are highly delicate, 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. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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