For underwater searches, we recommend UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42, which is very powerful 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 highly effective for retrieving in water due to their strong attraction capability. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 weighing 1800.00 grams with a pulling force of ~601.00 kg is a great choice for finding 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 attraction strength. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 has a pulling force of approximately ~601.00 kg, making it a effective solution 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 sliding 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 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 with a lifting capacity of ~601.00 kg, maximum power are achieved with the top attachment, while the side attachment 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 lifting force in a perpendicular manner. In a situation where the force acts parallelly, the magnet's lifting capacity 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.

In addition to immense power, 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,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They exhibit 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 a wide range of shapes and sizes, which amplifies their universality in usage.
  • Key role in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical equipment and various technologically advanced devices.

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 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,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Possible danger to health from tiny fragments of magnets can be dangerous, when accidentally ingested, which is particularly important in the aspect of protecting young children. Additionally, small elements of these products can be problematic in medical diagnosis when they are in the body.

Caution with Neodymium Magnets

Magnets made of neodymium are highly delicate, they easily break as well as can become damaged.

Magnets made of neodymium are fragile as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

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

Neodymium magnets produce 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 damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Never bring neodymium magnets close to a phone and GPS.

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

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

 It is essential to keep neodymium magnets away from 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.

Neodymium magnets can demagnetize at high temperatures.

Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

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

So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very strong neodymium magnets?.
