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.
Safety Guidelines with Neodymium Magnets
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
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.
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. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.
Neodymium magnets should not be around children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Keep neodymium magnets as far away as possible 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.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

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.
Keep neodymium magnets away from people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Neodymium magnets are especially fragile, resulting in damage.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Dust and powder from neodymium magnets are 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.
