For underwater searches, we recommend UMP 29x10 [M5] GW, which is very powerful and has an impressive magnetic pulling force of approximately ~32.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Neodymium magnets are ideal for searching in water due to their high lifting force. UMP 29x10 [M5] GW weighing 0.10 grams with a pulling force of ~32.00 kg is a perfect solution for finding 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 29x10 [M5] GW has a pulling force of approximately ~32.00 kg, making it a powerful tool for recovering 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 29x10 [M5] GW with a lifting capacity of ~32.00 kg, maximum power are achieved with the upper holder, while the side attachment offers only 10%-25% 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 pulling 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.

Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

  • They do not lose their strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic sources,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They have exceptionally 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...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Key role in advanced technologically fields – find application in hard drives, electric drive mechanisms, medical equipment and various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Potential hazard to health from tiny fragments of magnets are risky, when accidentally ingested, which becomes significant in the context of children's health. It's also worth noting that miniscule components of these devices have the potential to complicate diagnosis in case of swallowing.

Precautions

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

Strong magnetic fields emitted by neodymium magnets can damage 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. You should especially avoid placing neodymium magnets near 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.

Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.

Neodymium magnets jump and also clash mutually within a distance of several to around 10 cm from each other.

The magnet is coated with nickel - be careful 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 most powerful, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

Dust and powder from neodymium magnets are highly flammable.

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

Magnets made of neodymium are highly fragile, they easily break as well as can become damaged.

Magnets made of neodymium are delicate as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Never bring neodymium magnets close to a phone and 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.

Neodymium magnets should not be near 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

  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. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

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