Neodymium iron boron magnets are also called powerful magnets, permanent magnets, etc., which are magnets that can maintain their own magnetism for a long time. Will the NdFeB magnet demagnetize after a long time?

Many people know the characteristics of magnets, which can attract iron. Physically, magnets can attract objects made of iron, nickel and cobalt. NdFeB magnets are used in many other ways, and they can affect charged particles and electrical conductors.

Magnets can convert electrical energy into mechanical energy, which in turn can also convert mechanical energy into electrical energy. Because of this characteristic, the status of magnets in modern industry cannot be replaced, and they are widely used in electrical motors, electronics, mechanical equipment and other fields.

There are two main factors that affect the magnetic properties of strong magnets, temperature and oxidation. When the temperature exceeds the maximum operating temperature range of the permanent magnet, the magnetism of the permanent magnet is weakened or even disappeared; when the plating layer is damaged, the inner part is oxidized,

The magnetic properties of permanent magnets will also be weakened.

If they are not exposed to any of these conditions, permanent magnets will still lose their magnetic properties, but this degradation is very slow, decreasing by one percentage point every ten years, so as long as they are used correctly, there is no need to worry about the demagnetization of neodymium iron boron magnets. of.
