For exploring rivers and lakes, we recommend UMP 79x50 [M8] GW, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~340.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Magnetic holders are highly effective for searching in water environments due to their powerful strength. UMP 79x50 [M8] GW weighing 1.95 grams with a pulling force of ~340.00 kg is a perfect solution for recovering lost treasures.
When choosing a magnetic holder for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 79x50 [M8] GW has a pulling force of approximately ~340.00 kg, making it a effective solution for recovering 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 sliding force of a magnetic holder 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 79x50 [M8] GW with a lifting capacity of ~340.00 kg, full capabilities are achieved with the top attachment, while the side holder offers only 10%-25% of the declared force.
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 perpendicular manner. In a situation where the sliding occurs, the magnet's attraction force can be 5 times lower! Any gap between the magnet and the plate can cause a reduction in the lifting force.

Compilation of suggested goods

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose power over time. 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 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...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
  • Significant importance in the industry of new technologies – find application in hard drives, electric drive mechanisms, medical apparatus and other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also 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 reduction in strength (although it is worth noting that this is dependent on the shape 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 associated with microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting young children. Furthermore, tiny parts of these devices can be problematic in medical diagnosis when they are in the body.

Handle Neodymium Magnets with Caution

  Do not give neodymium magnets to children.

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.

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

Keep neodymium magnets away from 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.

Under no circumstances should neodymium magnets be brought close to 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.

Keep neodymium magnets away from TV, wallet, and computer HDD.

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

Neodymium magnets are particularly fragile, which leads to shattering.

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.

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.

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.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
