Shopping tips

For exploring rivers and lakes, we recommend UMP 75x24 [M8+M10] GW F 200 kg, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~280 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.
Magnetic holders are highly effective for searching in water environments due to their high lifting force. UMP 75x24 [M8+M10] GW F 200 kg weighing 900 grams with a pulling force of ~280 kg is a perfect solution for recovering lost treasures.
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 75x24 [M8+M10] GW F 200 kg has a pulling force of approximately ~280 kg, making it a powerful tool for recovering objects with significant mass. Remember that the maximum strength 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 perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 75x24 [M8+M10] GW F 200 kg with a pulling force of ~280 kg, full capabilities are achieved with the upper holder, while the side holder offers only one-fourth to one-quarter of the stated power.
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 pulling force in a perpendicular manner. In a situation where the sliding occurs, the magnet's lifting capacity can be five times lower! Any gap between the magnet and the plate can cause a reduction in the attraction force.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

  • They retain their full power for nearly ten years – the loss is just ~1% (based on simulations),
  • They remain magnetized despite exposure to magnetic noise,
  • In other words, due to the shiny silver coating, the magnet obtains an aesthetic appearance,
  • Magnetic induction on the surface of these magnets is impressively powerful,
  • With the right combination of magnetic alloys, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the form),
  • With the option for tailored forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
  • Key role in modern technologies – they find application in hard drives, electromechanical systems, healthcare devices and sophisticated instruments,
  • Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,

Disadvantages of neodymium magnets:

  • They may fracture when subjected to a strong impact. If the magnets are exposed to physical collisions, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall durability,
  • They lose magnetic force at elevated temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • They rust in a humid environment. For outdoor use, we recommend using moisture-resistant magnets, such as those made of non-metallic materials,
  • Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing holes directly in the magnet,
  • Health risk linked to microscopic shards may arise, especially if swallowed, which is crucial in the health of young users. Moreover, miniature parts from these devices have the potential to interfere with diagnostics after being swallowed,
  • Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Exercise Caution with Neodymium Magnets

Neodymium magnets are especially fragile, resulting in their breakage.

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.

Keep neodymium magnets as far away as possible from GPS and smartphones.

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 are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

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

Dust and powder from neodymium magnets are highly 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.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can demagnetize 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 are the strongest magnets ever created, and their strength can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

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

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

The magnet coating is made of nickel, so be cautious 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Pay attention!
