For underwater searches, we recommend UMP 97x40 [M8+M10] GW F300 Lina / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~380 kg. This model is perfect for locating metal objects at the bottom of water bodies.

Neodymium magnets are highly effective for retrieving in water environments due to their powerful strength. UMP 97x40 [M8+M10] GW F300 Lina / N38 weighing 2200 grams with a pulling force of ~380 kg is a perfect solution for recovering 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 lifting force. UMP 97x40 [M8+M10] GW F300 Lina / N38 has a pulling force of approximately ~380 kg, making it a effective solution 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 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 97x40 [M8+M10] GW F300 Lina / N38 with a lifting capacity of ~380 kg, full capabilities are achieved with the upper holder, while the side holder offers only 10%-25% of the stated power.

he Lifting 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 vertical manner. In a situation where the force acts parallelly, the magnet's attraction force can be 5 times lower! Any gap between the magnet and the plate can cause a reduction in the attraction force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their notable magnetism, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (according to literature),
They show superior resistance to demagnetization from outside magnetic sources,
Because of the lustrous layer of nickel, the component looks aesthetically refined,
They have exceptional magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in diverse shapes and sizes, which expands their functional possibilities,
Important function in modern technologies – they are utilized in computer drives, electric motors, medical equipment and other advanced devices,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of rare earth magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and increases its overall robustness,
They lose strength at high temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to wet conditions can rust. Therefore, for outdoor applications, it's best to use waterproof types made of coated materials,
Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing complex structures directly in the magnet,
Potential hazard related to magnet particles may arise, in case of ingestion, which is significant in the protection of children. Furthermore, minuscule fragments from these products might interfere with diagnostics if inside the body,
In cases of tight budgets, neodymium magnet cost is a challenge,

Notes with Neodymium Magnets

Keep neodymium magnets away from children.

Neodymium magnets are not toys. Do not allow children to play 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.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Strong 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

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 jump and also clash mutually within a radius of several to around 10 cm from each other.

Neodymium magnetic are especially fragile, which leads to shattering.

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.

Neodymium magnets are not recommended for 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.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, 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 the most powerful magnets ever created, and their strength can shock you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Safety precautions!
