For underwater searches, we recommend UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~601 kg. This model is ideal for retrieving metal objects at the bottom of water bodies.

Magnetic holders are ideal for searching in water due to their powerful strength. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 weighing 1800 grams with a pulling force of ~601 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 lifting force. UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 has a pulling force of approximately ~601 kg, making it a effective solution for retrieving 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 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 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 with a lifting capacity of ~601 kg, full capabilities are achieved with the upper holder, while the side holder offers only one-fourth to one-quarter of the declared force.

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 pulling force in a perpendicular manner. In a situation where the force acts parallelly, the magnet's attraction force can be 5 times lower! Any gap between the magnet and the plate can cause a reduction in the attraction force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They do not lose their magnetism, even after nearly 10 years – the decrease of lifting capacity is only ~1% (according to tests),
They show strong resistance to demagnetization from external magnetic fields,
Because of the brilliant layer of gold, the component looks high-end,
They possess strong magnetic force measurable at the magnet’s surface,
Thanks to their exceptional temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in diverse shapes and sizes, which expands their functional possibilities,
Important function in new technology industries – they serve a purpose in HDDs, electric motors, healthcare devices and high-tech tools,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They may fracture when subjected to a sudden impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage while also enhances its overall strength,
High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Magnets exposed to moisture can rust. Therefore, for outdoor applications, it's best to use waterproof types made of non-metallic composites,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is risky,
Possible threat due to small fragments may arise, especially if swallowed, which is crucial in the context of child safety. Additionally, minuscule fragments from these magnets might complicate medical imaging when ingested,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Caution with Neodymium Magnets

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.

Never bring neodymium magnets close to a phone and GPS.

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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise 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.

The magnet is coated with nickel - be careful 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

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.

Maintain neodymium magnets away from children.

Neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

Neodymium magnets will jump and also clash together 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.

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

Neodymium magnets are characterized by considerable 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 collision between the magnets, small metal fragments can be dispersed in different directions.
