For exploring rivers and lakes, we recommend UMP 79x50 [M8] GW, which is very powerful and has an impressive magnetic pulling force of approximately ~340.00 kg. This model is perfect for retrieving metal objects at the bottom of water bodies.
Magnetic holders are ideal for searching in water due to their powerful strength. UMP 79x50 [M8] GW weighing 1.95 grams with a pulling force of ~340.00 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 lifting force. UMP 79x50 [M8] GW has a pulling force of approximately ~340.00 kg, making it a effective solution for retrieving heavier items. 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 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 79x50 [M8] GW with a pulling force of ~340.00 kg, full capabilities are achieved with the top attachment, while the side holder offers only 10%-25% of the stated power.
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 lifting capacity can be five times lower! Any gap between the magnet and the plate can cause a reduction in the lifting force.

Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

  • They do not lose strength over time - after about 10 years, their strength decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic sources,
  • In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They have 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 expands the range of their possible uses.
  • Wide application in the industry of new technologies – are utilized in computer drives, electric drive mechanisms, medical devices or other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
  • High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
  • Due to their susceptibility to corrosion in a humid environment, we suggest 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
  • Possible danger arising from small pieces of magnets pose a threat, when accidentally ingested, which is particularly important in the context of children's health. It's also worth noting that small elements of these devices are able to be problematic in medical diagnosis after entering the body.

Be Cautious with Neodymium Magnets

Neodymium magnets are characterized by being fragile, which can cause them to become damaged.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Avoid contact with neodymium magnets if you have a nickel 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.

Neodymium magnets are the strongest magnets ever created, and their power can surprise you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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 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, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

 It is important to maintain neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in 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.

Neodymium magnets should not be near people with pacemakers.

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

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

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that magnets have been found 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.

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
