For exploring rivers and lakes, we recommend UMP 67x28 [M8+M10] GW F120 Lina / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~180 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.

Neodymium magnets are efficient for searching in water environments due to their powerful strength. UMP 67x28 [M8+M10] GW F120 Lina / N38 weighing 700 grams with a pulling force of ~180 kg is a perfect solution for recovering metallic findings.

When choosing a magnet for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the lifting force. UMP 67x28 [M8+M10] GW F120 Lina / N38 has a pulling force of approximately ~180 kg, making it a powerful tool 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 sideways 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 Lina / N38 with a lifting capacity of ~180 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 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 attraction force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their strength (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic field,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They possess very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
Wide application in modern technologies – are used in computer drives, electric motors, medical equipment and other highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break when subjected to a strong 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,
High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction 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,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk arising from small pieces of magnets pose a threat, if swallowed, which becomes significant in the aspect of protecting young children. It's also worth noting that miniscule components of these products are able to complicate diagnosis when they are in the body.

Be Cautious with Neodymium Magnets

Keep neodymium magnets away from children.

Remember that 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.

Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

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.

Keep neodymium magnets as far away as possible from GPS and smartphones.

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

The magnet is coated with nickel. Therefore, exercise caution if you have an 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnetic are noted for their fragility, which can cause them to 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.

Neodymium magnets are the strongest magnets ever invented. Their power can shock you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to put fingers between magnets or in their path when attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.

Be careful!
