For exploring rivers and lakes, we recommend UMP 94x28 [3xM10] GW F300 GOLD Lina / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~330 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.

Magnetic holders are efficient for retrieving in water environments due to their strong attraction capability. UMP 94x28 [3xM10] GW F300 GOLD Lina / N38 weighing 1600 grams with a pulling force of ~330 kg is a perfect solution for recovering metallic findings.

When choosing a magnetic holder for underwater searches, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 94x28 [3xM10] GW F300 GOLD Lina / N38 has a pulling force of approximately ~330 kg, making it a effective solution for retrieving objects with significant mass. Remember that the full power is achieved with the upper holder, while the side attachment offers only 10%-25% of that power.

The sideways 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 94x28 [3xM10] GW F300 GOLD Lina / N38 with a lifting capacity of ~330 kg, maximum power are achieved with the upper holder, while the side holder offers only 10%-25% of the stated power.

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 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 result in a reduction in the lifting force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their pulling strength, neodymium magnets provide the following advantages:

They do not lose their strength around ten years – the decrease of lifting capacity is only ~1% (according to tests),
They protect against demagnetization induced by external electromagnetic environments very well,
Because of the lustrous layer of silver, the component looks aesthetically refined,
Magnetic induction on the surface of these magnets is impressively powerful,
Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which broadens their application range,
Significant impact in new technology industries – they are used in computer drives, rotating machines, healthcare devices and sophisticated instruments,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which makes them useful in small systems

Disadvantages of neodymium magnets:

They are fragile when subjected to a heavy impact. If the magnets are exposed to shocks, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and additionally increases its overall robustness,
They lose power at high temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a wet environment. For outdoor use, we recommend using moisture-resistant magnets, such as those made of non-metallic materials,
Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
Possible threat due to small fragments may arise, if ingested accidentally, which is important in the context of child safety. Additionally, tiny components from these products have the potential to disrupt scanning when ingested,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Precautions

Neodymium magnets should not be in the vicinity youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets are extremely fragile, they easily break and can become damaged.

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. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

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

The magnet is coated with nickel. Therefore, exercise caution if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a serious pressure or even a fracture.

Keep neodymium magnets away from the wallet, computer, and TV.

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets can become demagnetized 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.

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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.

Caution!
