Adjustable Permanent Magnet Description

The adjustable permanent magnet produces a constant magnetic field which is a great advantage over the electromagnet, but most permanent magnets feature a fixed structure and magnetic field, which limits applications. Our company is dedicated to the research and development of a variety of permanent magnets with adjustable magnetic fields, air gaps, magnetic field strength, and stable uniform zones. The adjustable permanent magnet thus has a similar functionality to the electromagnet, while also having a reduced size.
