Abstract

Considering magnetic hysteresis with Hysteron model, approximate expressions were derived in reference to properties of several magnetic materials. In the case of using JMAG, it is convenient to use user’s subroutines because modifications can be easily made with user’s intention. Therefore interface between solver and subroutine was made. These lead to the completion of main program, by which magnetization, magnetic field and magnetic energy can be calculated based on magnetic flux density.
