Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their strength (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources extremely well,
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...
Thanks to the flexibility in shaping or the ability to adapt to specific requirements – 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 drive mechanisms, medical apparatus or other highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break 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 at the same time increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form 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,
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 can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. Additionally, miniscule components of these products can complicate diagnosis after entering the body.

Handle with Care: Neodymium Magnets

Neodymium magnetic are particularly fragile, resulting in their breakage.

Magnets made of neodymium are extremely delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

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

Magnets will bounce and also clash together within a distance of several to almost 10 cm from each other.

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these 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. Once crushed into fine powder or dust, this material becomes highly flammable.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise you.

Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.

Never bring neodymium magnets close to a phone and GPS.

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

The magnet is coated with nickel. Therefore, exercise caution if you have an 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.

Magnets are not toys, children should not play with them.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

Neodymium magnets can become demagnetized at high temperatures.

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

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