Analyser for calculating the magnetic field generated by a system of particles

摘要

Provided is an analysis technique which enables preferred analysis of magnetic phenomenon in a simulation. An analyzer (100) includes a magnetic moment application unit (110) configured to apply a magnetic moment to a particle system defined in a virtual space, a magnetic field calculation unit (121) configured to calculate a magnetic physical quantity related to the particle system including particles, to which the magnetic moment is applied by the magnetic moment application unit (110), and a particle state calculation unit (124) configured to numerically calculate a governing equation, which governs the movement of each particle, using the calculation result in the magnetic field calculation unit (121). The magnetic field calculation unit (121) numerically calculates an induction magnetic field using induced magnetization induced in each particle due to a time variation in an external magnetic field and a magnetic field obtained by interaction between magnetic moments based on the induced magnetization.
