For underwater searches, we recommend UMP 67x28 [M8+M10] GW F120 kg / N38, 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 retrieving in water due to their high lifting force. UMP 67x28 [M8+M10] GW F120 kg / N38 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 67x28 [M8+M10] GW F120 kg / N38 has a pulling force of approximately ~${capacity} kg, making it a powerful tool for retrieving heavier items. Remember that the maximum strength is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sliding force of a magnet is typically lower than the adhesive force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 67x28 [M8+M10] GW F120 kg / N38 with a pulling force of ~${capacity} kg, full capabilities are achieved with the upper holder, while the side holder offers only one-fourth to one-quarter of the stated power.
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 pulling force in a perpendicular 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 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 strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the glossy nickel, gold, or silver finish, 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 shape) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
  • Key role in the industry of new technologies – are used in HDD drives, electric motors, medical apparatus or other highly developed apparatuses.

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 metal holder. 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 strength 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Health risk arising from small pieces of magnets are risky, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that miniscule components of these devices are able to be problematic in medical diagnosis in case of swallowing.

Precautions

Neodymium magnets are the strongest magnets ever created, and their power can surprise 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.

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.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

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

Magnets may crack or crumble with uncontrolled connecting to each other. You can't approach them to each other. At a distance less than 10 cm you should hold them very strongly.

Magnets made of neodymium are incredibly delicate, they easily fall apart and can crumble.

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. 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.

The magnet coating is made of nickel, so be cautious if you have an 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.

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.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Keep neodymium magnets away from people with pacemakers.

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.

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

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.

Please see the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
