摘要

PROBLEM TO BE SOLVED: To provide a particle behavior analyzer that can easily and precisely calculate the behavior of the particle of a magnetic body taking into consideration the change in a magnetic field due to the travel and rotation of a magnetic field application section, and can easily display the behavior of particles that is the analysis result and magnetic field data at that.;SOLUTION: A calculation section 112a of magnetic force, acting on the magnetic particles of the particle behavior analyzer, comprises a setting section 116 of a coordinates system after the magnetic field applying section travels; a calculation section 117 of the mapping of magnetic field data; a calculation section 118 of the magnetization of particles; a calculation section 119 of magnetic force by the magnetic field applied; and a calculation section 120 of magnetic force by means of particles. The calculation section 117 obtains the magnetic field data after the magnetic field application section travels, by mapping magnetic field data at a basic magnetic field application position from the coordinate system of the basic application magnetic field to a coordinates system, after the magnetic field application section has traveled. A calculation section 118 obtains the magnetization of particles. The calculation section 119 obtains the magnetic force acting on the particles, based on the magnetic field data. The calculation section 120 obtains the mutual magnetic interaction force among particles.;COPYRIGHT: (C)2007,JPO&INPIT
