For exploring rivers and lakes, we recommend UMP 107x40 [M8+M10] GW F 400 kg / N38, which is very powerful and has an impressive magnetic pulling force of approximately ~480 kg. This model is ideal for locating metal objects at the bottom of water bodies.

Magnetic holders are efficient for retrieving in water due to their powerful strength. UMP 107x40 [M8+M10] GW F 400 kg / N38 weighing 2350 grams with a pulling force of ~480 kg is a great choice for finding lost treasures.

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 107x40 [M8+M10] GW F 400 kg / N38 has a pulling force of approximately ~480 kg, making it a effective solution for retrieving heavier items. Remember that the maximum strength is achieved with the upper holder, 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 107x40 [M8+M10] GW F 400 kg / N38 with a lifting capacity of ~480 kg, full capabilities 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 test conditions, using a smooth S235 low-carbon steel plate with a thickness of 10 mm, with the application of pulling 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 magnetic efficiency, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (in laboratory conditions),
They remain magnetized despite exposure to magnetic surroundings,
In other words, due to the shiny silver coating, the magnet obtains an professional appearance,
They possess intense magnetic force measurable at the magnet’s surface,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
With the option for customized forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
Key role in cutting-edge sectors – they are used in data storage devices, electromechanical systems, diagnostic apparatus and sophisticated instruments,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of neodymium magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to external force, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time reinforces its overall strength,
High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on height). 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,
Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of protective material for outdoor use,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is restricted,
Health risk due to small fragments may arise, if ingested accidentally, which is notable in the protection of children. Furthermore, miniature parts from these magnets may interfere with diagnostics after being swallowed,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Exercise Caution with Neodymium Magnets

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and 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.

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 are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

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

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

If you have a nickel allergy, avoid contact with neodymium magnets.

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

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

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

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 keep neodymium magnets out of reach from youngest 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.

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 especially delicate, which leads to shattering.

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. 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.

Warning!

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