    Abstract

    Experimental, numerical, and theoretical investigations have been carried out on statics of a magnetic bead chain in the magnetic filed. Chains formed on a solenoid coil were observed and chain lengths and slant angles were measured by a digital microscope. It was deduced that (1) the chain length depends on both the weight of magnetic particles and the magnetic flux density; (2) chains have inclinations in the inclined magnetic field and that inclinations of the chains are enlarged by the gravitational force. These static configurations of chains are approximately determined to minimize the total potential energy that consisted of the gravitational and magnetic potential energy. These characteristics were qualitatively confirmed by the numerical calculation with the two-dimensional Distinct Element Method. The investigation is expected to be utilized for the improvement of the two-component magnetic brush development system in electrophotography.
