PROBLEM TO BE SOLVED: To provide a precise, high-speed vector hysteresis magnetic field analysis method requiring only less amount of memory.;SOLUTION: In a magnetic field analysis equation, related to magnetic vector potential with a magnetization vector as a source term, the estimation magnetization vector at certain time, is set, the amount of variation of the magnetic vector potential is obtained, the amount of variations in magnetic flux density is calculated from the amount, and a tensor for relating the amount of variations in an arbitrary scalar hysteresis model and a magnetization vector to that of a magnetic field vector is used together, thus the amount of variations in magnetization and magnetic fields from that of the magnetic flux density are calculated and the magnetization vector is updated. By repeating this process, the convergence solution of the magnetic vector potential that takes into consideration the vector hysteresis characteristics is obtained, and the convergence solution of the magnetization vector, and magnetic field vector is calculated.;COPYRIGHT: (C)2008,JPO&INPIT
