Overview

JMAG can create magnets with coercive force distributions and/or residual magnetic flux density distributions such as magnets using an alloying process using grain boundary diffusion (Fig. a). JMAG can also evaluate thermal demagnetization since the coercive force distribution and residual magnetic flux density distribution can take into account temperature dependence.
This document describes how to set a magnet material with coercive force and residual magnetic flux density taking into account temperature dependence.
