摘　　要：在导线静止的转动参考系中讨论单极电机的原理，发现在此转动系中不仅有磁场而且存在径向电场．此外，在导体回路的磁铁部分中的一个荷电粒子受到的径向电场力与由于磁铁相对于转动系运动而受到的洛仑兹力相抵消．The principle of the monopole electric generator is discussed in the rotating reference system in which the conducting wire is at rest.It is found that in this system there exist not only a magnetic field but also a radial electric field.Besides,the force exerted by the radial electric field on the charged particle in the magnet part of the conducting loop is canceled by the Lorentz force due to the relative motion of the magnet with respect to the rotating reference system.Therefore the resultant electromotive force of the generater is induced by the force exerted by the radial electric field on the charged particle in the conducting wire.
