It is crucial to choose neodymium magnets with the appropriate strength for the intended use, and to check the suitability of the cover with the operating conditions, in order to guarantee maximum performance and safety.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their strength (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic sources,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They exhibit very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
Wide application in advanced technologically fields – find application in hard drives, electric motors, medical devices or various technologically advanced devices.

Disadvantages of neodymium magnets:

They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk arising from small pieces of magnets pose a threat, when accidentally ingested, which becomes significant in the aspect of protecting young children. It's also worth noting that miniscule components of these magnets can be problematic in medical diagnosis when they are in the body.

Safety Precautions

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

Neodymium magnets will bounce and touch together within a distance of several to around 10 cm from each other.

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

Neodymium magnets are the strongest 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 extremely fragile, resulting in their cracking.

Neodymium magnets are characterized by significant fragility. Neodymium magnets 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.

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

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 become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Safety precautions!

In order for you to know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous very powerful neodymium magnets.
