PROBLEM TO BE SOLVED: To ask for the behavior of particle in the case having a plurality of magnetic field impression means with a sufficient accuracy simply. SOLUTION: A particle behavior analyzing apparatus includes a selecting section of impression magnetic field data which selects one of a plurality of prepared impression field data, a calculating section of the magnetization of the particle which asks for the magnetization of the particle, a calculating section of a magnetic force by the impression magnetic field which asks for the magnetic force which works to the particle, a calculating section of the magnetic force by the particle which searches for the magnetic mutual interaction force of the particles, and a calculating section of the magnetic force which works on the particle constituted of the calculating section of the magnetic force.
