也谈均匀磁场中旋转的中性轴对称导体上的电荷分布

The charge distribution on an axially symmetric conductor rotating in a uniform static magnetic field

严格证明了中性轴对称导体在均匀外磁场中旋转时 ,等势面为同轴圆柱面 ,并由电荷守恒定律证明该轴上的磁场精确等于外磁场B0 .同时还得出了该导体表面电荷密度的普遍公式 .

It is strictly proved that the equipotential surfaces of a neutral axially symmetric conductor rotating in a uniform static magnetic field are coaxial cylindrical surfaces.It is exactly showed that the magnetic field at the axis is equal to B 0 by using the conservation law of charge,general formula of charge surface density is given.
