What types are there? A permanent magnet is a material that can provide magnetic flux when magnetized with an applied magnetic field and its magnetism capability is characterized by two key parameters: remanence and coercitivity In general, the intrinsic coercitivity of a permanent magnet (Hcj ) is greater than 300kOe (in the CGS unit) or 24kA .
