For underwater searches, we recommend UMP 75x25 [M10x3] GW F200 PLATINIUM / N52, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~365 kg. This model is perfect for locating metal objects at the bottom of water bodies.

Magnetic holders are ideal for searching in water environments due to their high lifting force. UMP 75x25 [M10x3] GW F200 PLATINIUM / N52 weighing 900 grams with a pulling force of ~365 kg is a great choice for finding 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 75x25 [M10x3] GW F200 PLATINIUM / N52 has a pulling force of approximately ~365 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 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 75x25 [M10x3] GW F200 PLATINIUM / N52 with a lifting capacity of ~365 kg, maximum power are achieved with the upper holder, while the side attachment offers only one-fourth to one-quarter of the declared force.

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 sliding occurs, the magnet's attraction force can be 5x 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.

Apart from immense strength, neodymium magnets have the following advantages:

They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
They are extremely resistant to demagnetization by external magnetic sources,
Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
Significant importance in advanced technologically fields – find application in hard drives, electric motors, medical devices or very highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger to health from tiny fragments of magnets pose a threat, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that tiny parts of these devices are able to be problematic in medical diagnosis after entering the body.

Exercise Caution with Neodymium Magnets

The magnet coating is made of nickel, so be cautious if you have an 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.

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 joining of neodymium magnets is not under control, at that time they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should hold them very firmly.

Neodymium magnets can demagnetize 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.

Neodymium magnets are the most powerful magnets ever created, and their power can shock 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.

Neodymium magnets are highly susceptible to damage, resulting in breaking.

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. 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.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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 significant injuries, and even death.

Keep neodymium magnets away from GPS and smartphones.

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

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Dust and powder from neodymium magnets are highly 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.

Neodymium magnets are not recommended for people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
