When magnetic domains in a material are aligned so their magnetic fields add, the result is a net magnetism. Undesired magnetism can be eliminated or reduced with a demagnetizer, or degausser, which uses a high amplitude, high frequency AC magnetic field to randomize the domain orientation.
Magnet is widely used in industries like metallurgy, machinery, shipbuilding, electric power, mine, automobile manufacturing, rail transportation and so on. There is mainly 3 kinds of magnet, permanent magnet, electromagnet, permanent electromagnet. different magnet is suitable for different areas, and as a professional supplier of magnetic tools, JYC technology is is always providing customers appropriate solutions for our customers.
