对磁珠链在磁场中的静力学进行了实验、数值和理论研究。观察了在电磁线圈上形成的链，并测量了链的长度和倾斜角度。结果表明，链长与磁性粒子的密度和磁通密度有关。还澄清了链在倾斜磁场中具有倾斜度，并且链的倾斜度在重力作用下被放大。这些链的构型被确定为最小化由重力势能和磁势能组成的总势能。用离散元法的数值计算也证实了这些特性。
Experimental, numerical, and theoretical investigations have been carried out on statics of magnetic bead chain in magnetic field. Chains formed on a solenoid coil were observed and chain lengths and slant angles were measured. It was clarified that the chain length depends on both the density of magnetic particles and the magnetic flux density. It was also clarified that chains have inclinations in the inclined magnetic field and that the inclination of a chain is enlarged by the gravitational force. These configurations of chains are determined to minimize the total potential energy that consists of the gravitational and magnetic potential energy. These characteristics were also confirmed by the numerical calculation with the Distinct Element Method.
