For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 GOLD Lina / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~${capacity} kg. This model is perfect for retrieving metal objects at the bottom of water bodies.
Magnetic holders are efficient for searching in water environments due to their high lifting force. UMP 75x25 [M10x3] GW F200 GOLD Lina / N42 weighing ${weight} grams with a pulling force of ~${capacity} kg is a perfect solution for finding lost treasures.
When choosing a magnetic holder for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 75x25 [M10x3] GW F200 GOLD Lina / N42 has a pulling force of approximately ~${capacity} kg, making it a powerful tool for recovering objects with significant mass. Remember that the maximum strength is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sliding force of a magnet is typically lower than the perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 75x25 [M10x3] GW F200 GOLD Lina / N42 with a lifting capacity of ~${capacity} kg, full capabilities are achieved with the top attachment, while the side holder offers only one-fourth to one-quarter of the stated power.
he attraction force was measured under laboratory conditions, using a smooth S235 low-carbon steel plate with a thickness of 10 mm, with the application of pulling force in a perpendicular manner. In a situation where the force acts parallelly, 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 and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength 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 nickel, gold, or silver finish, 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 shape) even at temperatures of 230°C or higher...
  • 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 enhances their versatility in applications.
  • Key role in the industry of new technologies – find application in computer drives, electric motors, medical apparatus or very modern machines.

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,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Health risk associated with microscopic parts of magnets are risky, in case of ingestion, which is crucial in the context of children's health. Furthermore, tiny parts of these products have the potential to be problematic in medical diagnosis after entering the body.

Handle with Care: Neodymium Magnets

Keep neodymium magnets away from 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.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

Neodymium magnets bounce and also clash mutually within a distance of several to around 10 cm from each other.

Dust and powder from neodymium magnets are highly 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 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.

The magnet coating contains nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets 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. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnetic are incredibly delicate, they easily fall apart as well as can crumble.

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

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

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

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

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

 It is important to keep neodymium magnets away from youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
