For exploring rivers and lakes, we recommend UMP 67x28 [M8+M10] GW F120 kg / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~180.00 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 67x28 [M8+M10] GW F120 kg / N38 weighing 700.00 grams with a pulling force of ~180.00 kg is a great choice for finding metallic findings.
When choosing a magnet for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 67x28 [M8+M10] GW F120 kg / N38 has a pulling force of approximately ~180.00 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 perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 67x28 [M8+M10] GW F120 kg / N38 with a lifting capacity of ~180.00 kg, maximum power are achieved with the upper holder, while the side attachment offers only 10%-25% of the stated power.
he attraction force was measured under laboratory 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 attraction force can be five 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.

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

  • They do not lose power over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field very well,
  • 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 very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Key role in modern technologies – are used in hard drives, electric motors, medical equipment and very advanced devices.

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 metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
  • They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Possible danger arising from small pieces of magnets pose a threat, in case of ingestion, which is crucial in the context of child safety. It's also worth noting that small elements of these devices have the potential to complicate diagnosis after entering the body.

Handle Neodymium Magnets Carefully

 It is essential to maintain neodymium magnets away from children.

Neodymium magnets are not toys. Do not allow children to play 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.

Dust and powder from neodymium magnets are 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 highly susceptible to damage, leading to breaking.

Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will crack. Magnets made of neodymium 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, small metal fragments can be dispersed in different directions.

Under no circumstances should neodymium magnets be placed 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. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), 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 disruption to the magnets.

If you have a nickel allergy, avoid contact with neodymium magnets.

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

Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.

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.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Keep neodymium magnets away from GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
