摘　　要： 本文首先利用磁荷观点计算了旋转磁铁端面上的磁流,然后利用磁流的安培环路定理求出单极感应发电机回路中的电动势,并且指出回路中的电动势与回路的形状无关。利用磁荷观点还克服了使用相对论观点时对磁铁旋转速度过度限制、对磁铁端面磁场过度简化以及计算复杂的缺点。 In this paper, the magnetic current on the end face of the rotating magnet is calculated by using the viewpoint of magnetic charge. The electromotive force in the loop of a monopole induction generator is obtained by using Ampere＇s loop law of magnetic current, which pointed out that the electromotive force in the circuit is not related to the shape of the circuit. Using the viewpoint of magnetic charge, we also overcome the disadvantages in the method of using the relative theory, including the excessive restriction of the magnet＇s rotating speed, the excessive simplification of magnet field at the end face of magnet, and the complex computation.
