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.
Exercise Caution with Neodymium Magnets
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Magnetic 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.
The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are highly susceptible to damage, resulting in breaking.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If the joining of neodymium magnets is not controlled, at that time 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 firmly.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can surprise 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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
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.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
