For exploring rivers and lakes, we recommend UMP 107x40 [M8+M10] GW F400 Lina / N38, which is very powerful and has an impressive magnetic pulling force of approximately ~480.00 kg. This model is perfect for locating metal objects at the bottom of water bodies.
Neodymium magnets are efficient for searching in water environments due to their powerful strength. UMP 107x40 [M8+M10] GW F400 Lina / N38 weighing 2350.00 grams with a pulling force of ~480.00 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 lifting force. UMP 107x40 [M8+M10] GW F400 Lina / N38 has a pulling force of approximately ~480.00 kg, making it a powerful tool for recovering objects with significant mass. Remember that the maximum strength is achieved with the top attachment, 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 107x40 [M8+M10] GW F400 Lina / N38 with a pulling force of ~480.00 kg, full capabilities are achieved with the upper holder, while the side attachment offers only 10%-25% of the declared force.
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 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.

Compilation of suggested goods

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They are highly 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 possess 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...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Significant importance in advanced technologically fields – find application in hard drives, electric motors, medical apparatus and other highly developed apparatuses.

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 steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • They lose power 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
  • Possible danger to health from tiny fragments of magnets can be dangerous, in case of ingestion, which is crucial in the context of child safety. Additionally, miniscule components of these magnets can complicate diagnosis after entering the body.

We Recommend Caution with Neodymium Magnets

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

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

Do not bring neodymium magnets close to 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.

Neodymium magnets are highly delicate, they easily fall apart as well as can crumble.

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

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

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.

Even though magnets have been observed 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 most powerful magnets ever invented. Their strength can shock you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

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

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.

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

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

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

So that know how powerful neodymium magnets are and why they are so dangerous, read the article - Dangerous very powerful neodymium magnets.
