For exploring rivers and lakes, we recommend UMP 75x24 [M8+M10] GW F200 Lina / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~${capacity} kg. This model is perfect for locating metal objects at the bottom of water bodies.
Magnetic holders are efficient for searching in water due to their strong attraction capability. UMP 75x24 [M8+M10] GW F200 Lina / N38 weighing ${weight} grams with a pulling force of ~${capacity} kg is a perfect solution for finding 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 lifting force. UMP 75x24 [M8+M10] GW F200 Lina / N38 has a pulling force of approximately ~${capacity} kg, making it a effective solution for retrieving heavier items. Remember that the full power is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sliding force of a magnet is typically lower than the adhesive force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 75x24 [M8+M10] GW F200 Lina / N38 with a pulling force of ~${capacity} 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 pulling force in a vertical 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 attraction force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their strength (of the magnet). After approximately 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 nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They have exceptionally high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Wide application in modern technologies – are utilized in computer drives, electric drive mechanisms, medical apparatus or very advanced devices.

Disadvantages of neodymium magnets:

  • They can break as they are extremely 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,
  • High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction 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,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of children's health. Additionally, tiny parts of these products are able to hinder the diagnostic process when they are in the body.

Handle with Care: Neodymium Magnets

Dust and powder from neodymium magnets are highly 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.

Keep neodymium magnets away from 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.

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

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets are the strongest magnets ever invented. Their strength can surprise 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.

Neodymium magnetic are extremely delicate, they easily crack as well as can become damaged.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

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

If the joining of neodymium magnets is not controlled, at that time they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should have them extremely strongly.

Avoid contact with neodymium magnets if you have a nickel 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.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

  Do not give neodymium magnets to children.

Remember that 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.

So you are aware of why neodymium magnets are so dangerous, see the article titled How very dangerous are powerful neodymium magnets?.
