For exploring rivers and lakes, we recommend UMP 65x45 [M8]x2 GW F230+ Lina / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~230 kg. This model is ideal for locating metal objects at the bottom of water bodies.

Neodymium magnets are efficient for retrieving in water due to their powerful strength. UMP 65x45 [M8]x2 GW F230+ Lina / N38 weighing 1170 grams with a pulling force of ~230 kg is a great choice for finding metallic findings.

When choosing a magnet for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the attraction strength. UMP 65x45 [M8]x2 GW F230+ Lina / N38 has a pulling force of approximately ~230 kg, making it a effective solution for retrieving heavier items. Remember that the full power is achieved with the top attachment, while the side attachment offers only 10%-25% of that power.

The sliding 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 65x45 [M8]x2 GW F230+ Lina / N38 with a pulling force of ~230 kg, maximum power are achieved with the top attachment, while the side attachment offers only 10%-25% 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 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 and disadvantages of neodymium magnets NdFeB.

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
They are highly resistant to demagnetization caused by external magnetic sources,
Because of the lustrous layer of nickel, the component looks visually appealing,
They have exceptional magnetic induction on the surface of the magnet,
Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
With the option for tailored forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
Important function in advanced technical fields – they are utilized in HDDs, electromechanical systems, diagnostic apparatus along with sophisticated instruments,
Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which makes them ideal in small systems

Disadvantages of rare earth magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to physical collisions, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and reinforces its overall durability,
High temperatures may significantly reduce the holding force 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,
They rust in a moist environment. If exposed to rain, we recommend using moisture-resistant magnets, such as those made of plastic,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing holes directly in the magnet,
Safety concern from tiny pieces may arise, if ingested accidentally, which is notable in the family environments. Furthermore, minuscule fragments from these magnets may interfere with diagnostics after being swallowed,
High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Be Cautious with Neodymium Magnets

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

Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to put fingers between magnets or alternatively in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.

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

Magnets made of neodymium are known for being fragile, which can cause them to become damaged.

Neodymium magnetic are highly delicate, and by joining them in an uncontrolled manner, they will crumble. 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.

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

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

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

Neodymium magnets generate 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 flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

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 the strongest magnets ever invented. Their power can surprise you.

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