Most solid particles studied in industrial or basic researches are composed of diamagnetic or weak paramagnetic materials, and specific dynamical motions are not expected in these materials unless an ultra-high field is introduced. We proposed a new method to dynamically separate a mixture of heterogeneous particles into groups of different materials by a low field below 0.5T; magnetic susceptibility of the particles was obtained from particle velocity; material was identified as well from its magnetization obtained from velocity.The detection of magnetic susceptibility is based on a new finding that acceleration a of particle induced by a magnetic volume force is independent to its mass; a is uniquely determined by susceptibility of the material.
