Magnet FAQ

How much does the magnetism of permanent magnets lose in a year?

People often ask online, will the magnetic force of permanent magnets disappear? How many years can magnetism be used? How much magnetism will be lost after one year of use? And so on similar issues, today Dongguan Magnet Factory Carriage Xiaofu will introduce to you.
 
There are two main types of magnets: electromagnets and permanent magnets. Electromagnets are essentially magnets with switches. In the presence of current, they have magnetic force. When the current stops, they will lose their magnetic force.

Permanent magnets are just as you might infer from their names. Permanent magnets can generate and permanently maintain their own magnetic field. However, there are some factors that affect the strength of the magnet.
 
Generally speaking, under ideal conditions, permanent magnets will only lose a small part of their strength in a few years (that is, about 1% in 10 years). This percentage is so small that it does not significantly change its power. However, there are some conditions that can cause permanent magnets to lose their magnetism, such as temperature, environment, and so on.
