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 ~180 kg. This model is perfect for locating metal objects at the bottom of water bodies.

Neodymium magnets are highly effective for retrieving in water due to their powerful strength. UMP 67x28 [M8+M10] GW F120 kg / 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 attraction strength. UMP 67x28 [M8+M10] GW F120 kg / N38 has a pulling force of approximately ~180 kg, making it a powerful tool for recovering 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 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 kg / N38 with a pulling force of ~180 kg, maximum power are achieved with the upper holder, while the side attachment 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 sliding occurs, 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 as well as disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

They retain their magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
Their ability to resist magnetic interference from external fields is notable,
Thanks to the shiny finish and nickel coating, they have an aesthetic appearance,
The outer field strength of the magnet shows elevated magnetic properties,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which increases their functional possibilities,
Significant impact in modern technologies – they serve a purpose in HDDs, electric motors, diagnostic apparatus as well as sophisticated instruments,
Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,

Disadvantages of NdFeB magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time enhances its overall durability,
High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Due to corrosion risk in humid conditions, it is common to use sealed magnets made of plastic for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
Safety concern due to small fragments may arise, in case of ingestion, which is notable in the context of child safety. It should also be noted that miniature parts from these products have the potential to hinder health screening if inside the body,
Due to the price of neodymium, their cost is relatively high,

Exercise Caution with Neodymium Magnets

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other 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.

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. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Neodymium magnets will bounce and also clash together within a distance of several to around 10 cm from each other.

Under no circumstances should neodymium magnets be brought close to 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 - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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.

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.

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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

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.

Magnets made of neodymium are fragile and can easily break as well as shatter.

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

Exercise caution!

So that know how powerful neodymium magnets are and why they are so dangerous, read the article - Dangerous very powerful neodymium magnets.
