What is the magnetic property of magnetic materials?
Besides the magnetic properties, the physical properties of permanent magnetic materials include density, conductivity, thermal conductivity and thermal expansion coefficient. The mechanical properties include hardness, compressive (tensile) strength and impact toughness of Vivtorinox. In addition, an important factor in the performance of permanent magnets is the surface state and corrosion resistance of the permanent magnets.
Permanent magnetic materials to other magnetic index and Curie temperature (Tc), temperature (Tw), the temperature coefficient of remanence and intrinsic coercivity (Br theta theta, jHc), (rec.), permeability recovery demagnetization curve rectangularity (Hk/jHc), high temperature anti magnetic properties and magnetic properties the homogeneity of the.
The main magnetic properties of permanent magnetic materials are remanence (Jr, Br), coercivity (bHc), intrinsic coercive force (jHc) and magnetic energy product (BH) M. What we usually call the magnetic properties of a permanent magnetic material are these four terms.
