For underwater searches, we recommend UMP 65x45 [M8] GW, which is very powerful and has an impressive magnetic pulling force of approximately ~230.00 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 strong attraction capability. UMP 65x45 [M8] GW weighing 1150.00 grams with a pulling force of ~230.00 kg is a perfect solution for recovering metallic findings.
When choosing a magnetic holder for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 65x45 [M8] GW has a pulling force of approximately ~230.00 kg, making it a powerful tool for retrieving objects with significant mass. 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 adhesive force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 65x45 [M8] GW with a pulling force of ~230.00 kg, full capabilities are achieved with the top attachment, while the side holder offers only one-fourth to one-quarter of the declared force.
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 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.

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

  • They do not lose their power (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic sources 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,
  • Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) 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 many variants of shapes and sizes, which amplifies their universality in usage.
  • Key role in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical equipment or other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a strong 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 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 loss 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,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Potential hazard to health from tiny fragments of magnets can be dangerous, if swallowed, which becomes significant in the aspect of protecting young children. Additionally, tiny parts of these magnets are able to hinder the diagnostic process when they are in the body.

Handle Neodymium Magnets with Caution

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

 It is essential to maintain neodymium magnets out of reach from youngest children.

Neodymium magnets are not toys. Do not allow children to play 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 attract to each other, pinch the skin, and cause significant injuries.

If have a finger between or on the path of attracting magnets, there may be a severe cut or even a fracture.

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.

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

To use 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 can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Magnets made of neodymium are known for being fragile, which can cause them to shatter.

Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable 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.

Keep neodymium magnets away 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.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

In order to show why neodymium magnets are so dangerous, see the article - How dangerous are very strong neodymium magnets?.
