摘　　要：在已知磁铁之分子电流生于铁外的磁场强度 ,恰好就是它的等效磁荷生于铁外的磁场的基础上 ,证明细长永久磁铁的分子电流所受外磁场的总合力 ,也恰好等于它的等效磁荷所受外磁场作用力 ,推出等效“点磁荷”的库仑定律 。On the basis of having known that the magnetic filed intensity of the molecular electric current of the magnet generated outside the magnet is exactly the magnetic field of its equivalent magnetic charge generated outside the magnet ,this article is to prove that the total join forces the molecular electric current of the slim permanent magnet receives from the outer magnetic field ,is also equal to the applied forces its equivalent magnetic charge receives from the outer magnetic field ,and deduce the Coulomb's Law of the equivalent 'dot magnetic charge',and reveal the substance that magnetic pole interact on each other.
