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.
- Susceptibility to corrosion: They require a protective coating (e.g., nickel, zinc) to prevent rusting.
- 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.
Caution with Neodymium Magnets
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. Remember not to insert fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, can even cut off a finger or there can be a significant pressure or even a fracture.
Neodymium magnets should not be in the vicinity youngest children.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets are not recommended for people with pacemakers.
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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnetic are extremely fragile, they easily crack as well as can become damaged.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are the strongest magnets ever invented. Their strength can surprise you.

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.
The magnet is coated with nickel. Therefore, exercise caution 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.
