For exploring rivers and lakes, we recommend UMP 94x28 [3xM10] GW F300 GOLD / N38, which is very powerful and has an impressive magnetic pulling force of approximately ~330.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Magnetic holders are ideal for retrieving in water environments due to their strong attraction capability. UMP 94x28 [3xM10] GW F300 GOLD / N38 weighing 1600.00 grams with a pulling force of ~330.00 kg is a great choice for recovering lost treasures.
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 94x28 [3xM10] GW F300 GOLD / N38 has a pulling force of approximately ~330.00 kg, making it a effective solution 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 94x28 [3xM10] GW F300 GOLD / N38 with a pulling force of ~330.00 kg, maximum power are achieved with the upper holder, 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 force acts parallelly, the magnet's lifting capacity can be 5 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 their strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • 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 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 various forms and dimensions, which amplifies their universality in usage.
  • Wide application in advanced technologically fields – are used in computer drives, electric drive mechanisms, medical devices or various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They can break when subjected to a powerful 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,
  • High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape 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
  • Health risk to health from tiny fragments of magnets are risky, if swallowed, which becomes significant in the aspect of protecting young children. It's also worth noting that miniscule components of these devices are able to be problematic in medical diagnosis when they are in the body.

Handle Neodymium Magnets Carefully

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

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

  Do not give neodymium magnets to youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

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. 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.

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

Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

The magnet coating contains nickel, so be cautious if you have a nickel 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 magnetic are especially fragile, which leads to damage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power 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.

Do not bring neodymium magnets close to GPS and smartphones.

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

Neodymium magnets can demagnetize 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.

To raise awareness of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
