For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 PLATINIUM / N52, which is very powerful and has an impressive magnetic pulling force of approximately ~365.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Magnetic holders are highly effective for retrieving in water due to their strong attraction capability. UMP 75x25 [M10x3] GW F200 PLATINIUM / N52 weighing 900.00 grams with a pulling force of ~365.00 kg is a perfect solution for finding metallic findings.
When choosing a magnet for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the lifting force. UMP 75x25 [M10x3] GW F200 PLATINIUM / N52 has a pulling force of approximately ~365.00 kg, making it a powerful tool for recovering heavier items. Remember that the maximum strength 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 75x25 [M10x3] GW F200 PLATINIUM / N52 with a pulling force of ~365.00 kg, full capabilities are achieved with the top attachment, while the side holder offers only 10%-25% of the stated power.
he Lifting force was measured under laboratory 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 sliding occurs, the magnet's attraction force can be five 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 immense power, neodymium magnets have the following advantages:

  • They do not lose strength over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
  • They have 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 or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
  • Wide application in the industry of new technologies – find application in HDD drives, electric motors, medical devices and other modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
  • High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the form 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 recommend 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
  • Potential hazard associated with microscopic parts of magnets can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. Additionally, tiny parts of these devices have the potential to complicate diagnosis after entering the body.

Safety Precautions

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

  Do not give neodymium magnets to children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Dust and powder from neodymium magnets are highly flammable.

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

Magnets made of neodymium are known for their fragility, which can cause them to shatter.

Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will break. 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.

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

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can demagnetize at high temperatures.

Even though 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength 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 the wallet, computer, and TV.

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. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

If the joining of neodymium magnets is not controlled, then they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should have them extremely strongly.

In order for you to know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
