For exploring rivers and lakes, we recommend UMP 75x24 [M8+M10] GW F200 Lina / N38, which is very powerful and has an impressive magnetic pulling force of approximately ~280 kg. This model is ideal for retrieving metal objects at the bottom of water bodies.

Neodymium magnets are highly effective for retrieving in water environments due to their high lifting force. UMP 75x24 [M8+M10] GW F200 Lina / N38 weighing 0.9 grams with a pulling force of ~280 kg is a perfect solution for recovering metallic findings.

When choosing a magnetic holder for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 75x24 [M8+M10] GW F200 Lina / N38 has a pulling force of approximately ~280 kg, making it a powerful tool for retrieving heavier items. Remember that the maximum strength is achieved with the top attachment, while the side attachment offers only 10%-25% of that power.

The sliding force of a magnetic holder 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 ~280 kg, maximum power are achieved with the top attachment, while the side attachment offers only 10%-25% 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 lifting force in a vertical manner. In a situation where the sliding occurs, 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.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They do not lose strength over time. After about 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic 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...
Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
Key role in modern technologies – are utilized in HDD drives, electric drive mechanisms, medical equipment and other advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking 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 loss 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,
Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Possible danger arising from small pieces of magnets can be dangerous, in case of ingestion, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these products have the potential to hinder the diagnostic process when they are in the body.

Exercise Caution with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

People with pacemakers are advised to avoid neodymium magnets.

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 are the most powerful 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 disruption to the magnets.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If you have a finger between or on the path of attracting magnets, there may be a serious cut or even a fracture.

Maintain neodymium magnets far 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.

Avoid contact with neodymium magnets if you have a nickel allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.

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.

Keep neodymium magnets away 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. You should especially avoid placing neodymium magnets near electronic devices.

Magnets made of neodymium are especially fragile, which leads to their breakage.

Neodymium magnetic are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Under no circumstances should neodymium magnets be brought 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.

Warning!

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