For exploring rivers and lakes, we recommend UMP 75x25 [M10x3] GW F200 GOLD / N42, which is exceptionally strong and has an impressive magnetic pulling force of approximately ~310 kg. This model is ideal for retrieving metal objects at the bottom of water bodies.

Neodymium magnets are efficient for searching in water environments due to their powerful strength. UMP 75x25 [M10x3] GW F200 GOLD / N42 weighing 900 grams with a pulling force of ~310 kg is a perfect solution for recovering lost treasures.

When choosing a magnet for water exploration, you should pay attention to the number of Gauss or Tesla value, which determines the lifting force. UMP 75x25 [M10x3] GW F200 GOLD / N42 has a pulling force of approximately ~310 kg, making it a powerful tool for recovering 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 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 GOLD / N42 with a lifting capacity of ~310 kg, full capabilities are achieved with the top attachment, 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 lifting force in a perpendicular manner. In a situation where the force acts parallelly, the magnet's attraction force can be 5x times lower! Any gap between the magnet and the plate can result in a reduction in the attraction force.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
They possess very high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve high 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 modern technologies – are used in hard drives, electric motors, medical apparatus or various technologically advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also 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,
Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk arising from small pieces of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. Additionally, small elements of these magnets can be problematic in medical diagnosis in case of swallowing.

Caution with Neodymium Magnets

You should keep neodymium magnets at a safe distance 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 damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Neodymium magnets are the strongest magnets ever invented. Their strength can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

People with pacemakers are advised to avoid neodymium magnets.

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.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Neodymium magnets are especially delicate, which leads to damage.

Neodymium magnets are characterized by considerable fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

It is important to keep neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.

The magnet coating contains nickel, so be cautious 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, 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.

If you have a finger between or on the path of attracting magnets, there may be a large cut or even a fracture.

Under no circumstances should neodymium magnets be brought 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.

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.
