For exploring rivers and lakes, we recommend UMP 94x40 [3xM10] GW F550 Silver Black Lina / N52, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~650.00 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.
Magnetic holders are ideal for retrieving in water environments due to their high lifting force. UMP 94x40 [3xM10] GW F550 Silver Black Lina / N52 weighing 2262.00 grams with a pulling force of ~650.00 kg is a perfect solution for finding 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 94x40 [3xM10] GW F550 Silver Black Lina / N52 has a pulling force of approximately ~650.00 kg, making it a powerful tool for retrieving 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 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 94x40 [3xM10] GW F550 Silver Black Lina / N52 with a pulling force of ~650.00 kg, full capabilities are achieved with the upper holder, while the side attachment offers only 10%-25% of the declared force.
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 force acts parallelly, the magnet's lifting capacity can be five times lower! Any gap between the magnet and the plate can cause a reduction in the lifting force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time. After 10 years, their power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field very well,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They exhibit very high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
  • Significant importance in modern technologies – are utilized in computer drives, electric drive mechanisms, medical apparatus or various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also 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 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,
  • Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Possible danger to health from tiny fragments of magnets are risky, in case of ingestion, which is crucial in the aspect of protecting young children. Furthermore, small elements of these magnets have the potential to complicate diagnosis after entering the body.

Precautions with Neodymium Magnets

You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.

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

Dust and powder from neodymium magnets are 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.

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

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

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.

Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can shock you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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

Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Keep neodymium magnets away from GPS and smartphones.

Strong 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 clearly indicate a small percentage of people who suffer from metal allergies such as 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.

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

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.

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
