MAGNETIC-FIELD ANALYSIS DEVICE AND MAGNETIC-FIELD ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic-field analysis device that efficiently executes magnetic-field analysis with sufficient accuracy to a system having a magnetic body.;SOLUTION: The magnetic-field analysis device 1 has a storage means and a calculation means. The storage means stores analysis conditions including a magnetization curve (a Potter-Schmulian equation) of a magnetic body and an equation of motion of a magnetic field. The calculation means calculates initial values and constants of coefficients and variables of the equation of motion of the magnetic field of particles, constituting the magnetic body, from the analysis conditions so as to calculate a solution of the equation of motion of the magnetic field. Then, the calculation means calculates the magnetic field at an arbitrary point in a space on the basis of the solution of the equation of motion of the magnetic field. The magnetic-field analysis device 1 calculates an arbitrary magnetic field in a space by using the calculation means on the basis of the equation of motion of the magnetic field and input information.;COPYRIGHT: (C)2011,JPO&INPIT
