For underwater searches, we recommend UMP 135x40 [M10+M12] GW F 600 kg / N38, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~680 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.

Magnetic holders are ideal for searching in water environments due to their powerful strength. UMP 135x40 [M10+M12] GW F 600 kg / N38 weighing 4300 grams with a pulling force of ~680 kg is a great choice 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 135x40 [M10+M12] GW F 600 kg / N38 has a pulling force of approximately ~680 kg, making it a powerful tool for retrieving objects with significant mass. 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 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 135x40 [M10+M12] GW F 600 kg / N38 with a pulling force of ~680 kg, full capabilities 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 vertical 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 result in a reduction in the lifting force.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
Their ability to resist magnetic interference from external fields is impressive,
Thanks to the glossy finish and nickel coating, they have an aesthetic appearance,
They possess intense magnetic force measurable at the magnet’s surface,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to profile),
With the option for fine forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
Significant impact in new technology industries – they find application in computer drives, electric motors, medical equipment and high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer strong power in tiny dimensions, which makes them useful in miniature devices

Disadvantages of magnetic elements:

They are fragile when subjected to a heavy impact. If the magnets are exposed to mechanical hits, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally strengthens its overall robustness,
They lose field intensity at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry 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 waterproof magnets, such as those made of plastic,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is difficult,
Possible threat from tiny pieces may arise, in case of ingestion, which is important in the protection of children. Furthermore, miniature parts from these assemblies might interfere with diagnostics when ingested,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle Neodymium Magnets Carefully

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.

Magnets made of neodymium are delicate and can easily crack and shatter.

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. 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.

Maintain neodymium magnets away from children.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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.

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets will 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, as a significant injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can surprise you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Caution!
