摘要

PROBLEM TO BE SOLVED: To provide a magnetic field analysis device, capable of performing magnetic field analysis at high speed and high precision.;SOLUTION: The magnetic field analysis device includes a magnetic field operation section which divides an object into many particles in order to calculate magnetic field affected on the object by numerically solving equations of motion of magnetic field which describes a relationship required to be satisfied by magnetic field affecting each particle in a form of equations of motion for every particle. Because adjustable parameters are introduced in equations of motion of magnetic field, the magnetic field operation section can adjust parameters so as to relax an effect that the nonlinearity of a magnetizing curve of the object exerts convergence of numerical solution.;COPYRIGHT: (C)2011,JPO&INPIT
