Electric Field and Charge Distribution of the Rotating Cylinder Conductor in a Magnetic Field

摘要

摘要:金属圆柱导体在匀强磁场中分别绕对称轴和垂直于对称轴的轴转动时，推导出电场和电荷密度的表达式，研究表明电荷密度与角速度有关与旋转半径无关，电场的大小正比于旋转半径.

Abstract:The expressions of electric field and charge density are worked out when a metal cylinder conductor rotates respectively around the symmetry axis and the axis perpendicular to the symmetry axis in a uniform magnetic field. Studies have shown that the charge density is relevant to the angular velocity while it has nothing to do with the radius of gyration which is proportional to the size of the electric field.
