Advantages and disadvantages of neodymium magnets
Neodymium magnets, also known as NdFeB magnets, are currently the strongest permanent magnets available on the market. Their exceptional magnetic properties make them suitable for various industries, technologies, and everyday life. Below are the key advantages:
- Immense attractive force: Even small neodymium magnets generate a very strong magnetic field.
- High coercivity: They are resistant to demagnetization by external magnetic fields.
- Wide operating temperature range: Standard neodymium magnets operate up to 80°C, with special versions up to 230°C.
- Variety of shapes and sizes: Available in many forms, making them easy to adapt to specific applications.
- Relatively low price compared to strength: They offer the best strength-to-price ratio among all magnets.
- Longevity: With proper use, they retain their magnetic properties for many years.
- Versatility of applications: From electric motors to speakers, separators, toys, and jewelry.
Despite numerous advantages, neodymium magnets also have certain disadvantages to consider:
- Brittleness: They are hard but brittle and prone to cracking or chipping upon impact.
- Limited operating temperature for standard versions: Above the Curie temperature, they lose their magnetic properties.
- Strong magnetic field can be dangerous: They can damage electronics, magnetic cards, and pose a risk of attracting metal objects with great force.
- Difficulties in mechanical processing: Due to their hardness and brittleness, processing them is complex.
Precautions
Keep neodymium magnets away from 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.
The magnet coating contains nickel, so be cautious 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 magnetic are noted for being fragile, which can cause them to crumble.
Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will crumble. 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.
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.
Make sure not to bring neodymium magnets close to the 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they 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.
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Keep neodymium magnets far 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 become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a significant injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a serious pressure or a fracture.
