Rolled Rubber Magnet Permanent Magnetic Materials Demagnetization curve

Date:2016-9-18 click:1059times

"Rolled Rubber Magnet" on the demagnetization curve of permanent magnet material, when the reverse magnetic field H is increased to a value bHc, magnetic induction of the magnet B 0, called the reverse magnetic field H is coercive coercive force of the material bHc; when a reverse magnetic field H = bHc, do not display the external magnetic flux, so the coercive force bHc permanent magnetic materials characterization capability or other external reverse magnetic field demagnetization resistance. Coercivity bHc is one of the important parameters of magnetic circuit design.
