8 Tips for the Use of Magnets

Magnets are closely related to our lives and have a wide range of applications. For example, magnets play an irreplaceable role in speakers, compasses, seals on refrigerator doors, door suctions, maglev trains, induction cookers, magnetic needles, mobile phones, jewelry, toys, leather bags, motors, generators, cranes, electric bells, etc. But how can we use magnets to maximize their effectiveness and avoid unnecessary troubles? Here are 8 tips for the use of magnets you can follow:

Tips for the Use of Magnets Tips for the Use of Magnets

Tip 1. When using a magnet, we should ensure that the workplace is clean to prevent small impurities such as iron filings from adsorbing on the magnet surface. This will affect the normal use of the product.

Tip 2. NdFeB magnets are suitable for storage in ventilated and dry rooms, because acids, alkalis, organic solvents, water, and high-temperature and humid environments are prone to corrosion of the magnet, causing the coating to fall off, the magnet to powdered and demagnetized. 

We should pay more attention to unplated products. During storage, the surface of the magnet can be properly coated with oil to prevent rust. This is also the main reason why we recommend anti-corrosion treatment on the surface of NdFeB magnets.

Tip 3. Store magnets away from magnetic-sensitive objects such as magnetic disks, magnetic cards, magnetic tapes, computer monitors, and watches. Electronic medical devices such as heart pacemakers should also be kept away from magnets. Otherwise, it will be very dangerous.

Tip 4. The magnet is hard and brittle. During transportation and installation, make sure that the magnet is not subject to severe impact. Improper methods can easily cause damage and cracking of the magnet.

Tip 5. The magnet should be shielded when transported in a magnetized state, especially for air transportation.

Tip 6. When assembling the magnets, be sure to take them out one by one carefully to avoid knocking and damage caused by the attraction between the magnets. In addition, it is necessary to prevent the flying debris generated by the attraction between the magnets from entering the eyes and causing harm to the human body.

Tip 7. NdFeB magnets are strong magnets. Since the magnetism of NdFeB magnets is very strong, when using this kind of magnets, you should avoid getting your hands or other parts of your body caught between the magnets. For larger NdFeB magnets, more attention should be paid to personal safety and protection.

Tip 8. Do not put the magnets with stronger magnetism (such as neodymium iron boron magnets and samarium cobalt magnets) together with magnets with weaker magnetism (such as aluminum nickel cobalt magnets and ferrite magnets).

In particular, the polarities of the magnets cannot be placed in the opposite direction. Otherwise, the magnet with weaker magnetism will be easily demagnetized.
