For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~${capacity} kg. This model is ideal for locating metal objects at the bottom of water bodies.
Magnetic holders are efficient for searching in water environments due to their powerful strength. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 weighing ${weight} grams with a pulling force of ~${capacity} kg is a perfect solution for recovering 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 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 has a pulling force of approximately ~${capacity} kg, making it a powerful tool for retrieving objects with significant mass. Remember that the maximum strength is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.
The sideways force of a magnetic holder is typically lower than the perpendicular force because it depends on the fraction of the magnetic field that interacts with the metal surface. In the case of UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 with a pulling force of ~${capacity} kg, full capabilities are achieved with the upper holder, while the side attachment offers only 10%-25% of the declared force.
he Lifting force was measured under laboratory 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 sliding occurs, the magnet's lifting capacity can be five times lower! Any gap between the magnet and the plate can result in a reduction in the attraction force.

Product suggestions

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time. After 10 years, their power decreases by only ~1% (theoretically),
  • They are extremely resistant to demagnetization by external magnetic field,
  • 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,
  • 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 various forms and dimensions, which enhances their versatility in applications.
  • Key role in the industry of new technologies – are used in computer drives, electric motors, medical equipment or very advanced devices.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. 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 form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment. For 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
  • Health risk arising from small pieces of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. Additionally, small elements of these magnets have the potential to complicate diagnosis after entering the body.

Notes with Neodymium Magnets

Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

Magnets made of neodymium are delicate as well as can easily crack and shatter.

Neodymium magnets are characterized by significant 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.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

 It is important to keep neodymium magnets out of reach from youngest children.

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.

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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar 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 primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets will bounce and also contact together within a distance of several to around 10 cm from each other.

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.
