Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose strength over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic sources extremely well,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
- Key role in modern technologies – find application in computer drives, electric motors, medical equipment or very advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Possible danger to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting young children. Additionally, small elements of these products have the potential to complicate diagnosis when they are in the body.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are not recommended for 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 attract to each other, pinch the skin, and cause significant swellings.
Magnets will attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a major injury may occur. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a serious pressure or even a fracture.
The magnet coating is made of nickel, so be cautious if you have an 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 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.
Neodymium magnetic are particularly fragile, which leads to their breakage.
Neodymium magnetic are extremely fragile, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
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.
Keep neodymium magnets far from children.
Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Neodymium magnets are the strongest magnets ever invented. Their power can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets produce intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
