For underwater searches, we recommend UMP 67x28 [M8+M10] GW F120 Lina / N38, which is very powerful 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 highly effective for retrieving in water due to their powerful strength. UMP 67x28 [M8+M10] GW F120 Lina / N38 weighing ${weight} grams with a pulling force of ~${capacity} kg is a perfect solution for finding metallic findings.
When choosing a magnet 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 Lina / N38 has a pulling force of approximately ~${capacity} kg, making it a effective solution for retrieving objects with significant mass. Remember that the maximum strength is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sliding force of a magnet is typically lower than the perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 67x28 [M8+M10] GW F120 Lina / N38 with a lifting capacity of ~${capacity} kg, full capabilities are achieved with the upper holder, while the side attachment 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 lifting force in a perpendicular manner. In a situation where the force acts parallelly, the magnet's lifting capacity can be 5 times lower! Any gap between the magnet and the plate can result in a reduction in the lifting force.

Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

  • They do not lose strength over time. After about 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • 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,
  • By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
  • Key role in modern technologies – find application in computer drives, electric motors, medical devices and other modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
  • High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
  • Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • 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 pose a threat, when accidentally ingested, which is crucial in the context of children's health. Additionally, miniscule components of these devices are able to complicate diagnosis in case of swallowing.

Caution with Neodymium Magnets

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

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

Neodymium magnets are noted for being fragile, which can cause them to crumble.

Neodymium magnets are characterized by significant fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

Dust and powder from neodymium magnets are 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 become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

The magnet is coated with nickel - be careful 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.

Avoid bringing neodymium magnets close to a phone or GPS.

Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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.

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

Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

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 swellings.

If the joining of neodymium magnets is not under control, at that time they may crumble and crack. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
