Magnetic field analytical device, magnetic field analytical manner and computer program

摘要

PPROBLEM TO BE SOLVED: To provide a magnetic field analyzer which requires no measurement of magnetic properties in high temperature region, and further can obtain more accurate analysis results than those of conventional method using the temperature-dependent relative magnetic permeability or room temperature BH curve. PSOLUTION: The magnetic field analyzer 1 computing distribution of magnetic flux density in an analysis object produced by external current and/or magnet, based on a numeric analysis model representing the analysis object, external current information and/or magnet information indicating direction and magnitude of the external current, and temperature information indicating temperature of the analysis object, includes: a receiving means for receiving magnetic properties indicating relation between magnetic field intensity and magnetic flux density of the analysis object at a given temperature; a memory means for storing susceptibility temperature property information showing relation between susceptibilities of a given temperature and another temperature; and a computing means for computing distribution of magnetic flux density based on these magnetic properties received by the receiving means, susceptibility temperature property information stored in the memory means, external current information and/or magnet information.
