摘　　要：电、磁和力虽说有物理量、物理现象上的差别,但有能量本质上的联系.列写回路电压方程时,电路元件上电压的量值与路径的绕向之间遵从:"顺者为正,逆者为负;"电流、磁通的动态规律是:"来者拒之,去者留之;"磁、电、力相互转化时的判断法则是:"左判受力,右判磁电."Force, magnetism and electricity have Energy essential relationships, though they have differences in physical measures and appearances. When a closed circuit＇ s equation is being established, component＇ s voltage polarity is plus if it is in the same direction as the closed way or it is negative. Electro-circuit and magnetic-circuit have the same peculiarity that they always stop their currents changing in dynamic process. The force＇ s direction is discovered by left hand rule, and the electricity＇ s and magnetism＇ s are found out all by right hand rule.
