For underwater searches, we recommend UMP 94x40 [3xM10] GW F550 Silver Black / N52, which is very powerful and has an impressive magnetic pulling force of approximately ~650 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.

Neodymium magnets are efficient for searching in water due to their powerful strength. UMP 94x40 [3xM10] GW F550 Silver Black / N52 weighing 2262 grams with a pulling force of ~650 kg is a perfect solution for recovering lost treasures.

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 94x40 [3xM10] GW F550 Silver Black / N52 has a pulling force of approximately ~650 kg, making it a powerful tool for retrieving heavier items. Remember that the full power 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 94x40 [3xM10] GW F550 Silver Black / N52 with a lifting capacity of ~650 kg, full capabilities are achieved with the upper holder, while the side holder offers only 10%-25% 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 vertical 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 attraction force.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from their consistent holding force, neodymium magnets have these key benefits:

Their strength remains stable, and after around 10 years, it drops only by ~1% (according to research),
They show strong resistance to demagnetization from outside magnetic sources,
Because of the lustrous layer of nickel, the component looks high-end,
They have exceptional magnetic induction on the surface of the magnet,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to build),
The ability for precise shaping as well as adaptation to custom needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
Significant impact in advanced technical fields – they serve a purpose in computer drives, electromechanical systems, clinical machines as well as high-tech tools,
Thanks to their power density, small magnets offer high magnetic performance, in miniature format,

Disadvantages of rare earth magnets:

They may fracture when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time increases its overall strength,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent deterioration 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 recommended to use sealed magnets made of protective material for outdoor use,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is risky,
Health risk due to small fragments may arise, especially if swallowed, which is crucial in the protection of children. Furthermore, small elements from these assemblies may disrupt scanning once in the system,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Be Cautious with Neodymium Magnets

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.

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.

Neodymium magnets are extremely fragile, resulting in breaking.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Keep neodymium magnets away from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.

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.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

Strong magnetic fields emitted by neodymium magnets can destroy 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. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that magnets have been found 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.

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.

It is essential to keep 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.

Be careful!

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