Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, 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 protect against demagnetization caused by external magnetic sources very well,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even 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 a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – are used in HDD drives, electric drive mechanisms, medical apparatus and other modern machines.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also 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,
- 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Possible danger to health from tiny fragments of magnets can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. Furthermore, small elements of these magnets can be problematic in medical diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material 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 the joining of neodymium magnets is not under control, then they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should have them extremely strongly.
The magnet is coated with nickel - be careful if you have an 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
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.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.
To handle 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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnetic are highly delicate, they easily fall apart as well as can crumble.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Keep neodymium magnets far from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
