For exploring rivers and lakes, 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 ideal for retrieving metal objects at the bottom of water bodies.

Neodymium magnets are ideal for searching in water environments due to their strong attraction capability. 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 powerful tool 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 sideways 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 97x40 [M8+M10] GW F300 Lina / N38 with a pulling force of ~380 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 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.

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (based on calculations),
Their ability to resist magnetic interference from external fields is notable,
In other words, due to the shiny gold coating, the magnet obtains an professional appearance,
They possess significant magnetic force measurable at the magnet’s surface,
With the right combination of materials, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
With the option for fine forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving design adaptation,
Significant impact in cutting-edge sectors – they are used in data storage devices, electric drives, diagnostic apparatus as well as high-tech tools,
Thanks to their power density, small magnets offer high magnetic performance, with minimal size,

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to shocks, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall resistance,
They lose strength at elevated temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to damp air can rust. Therefore, for outdoor applications, we advise waterproof types made of non-metallic composites,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is difficult,
Safety concern from tiny pieces may arise, when consumed by mistake, which is significant in the context of child safety. Moreover, miniature parts from these devices may hinder health screening after being swallowed,
High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which may limit large-scale applications

Exercise Caution with Neodymium Magnets

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.

Avoid bringing neodymium magnets close to a phone or GPS.

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

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Neodymium magnets should not be in the vicinity youngest children.

Remember that 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.

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.

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.

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.

If have a finger between or on the path of attracting magnets, there may be a large cut or a fracture.

Neodymium magnets are especially delicate, which leads to their breakage.

Magnets made of neodymium are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and 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.

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

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Pay attention!

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