摘　　要：推导了涡旋电场与它的电流源之间的关系 ,利用此关系和磁场的矢势计算了球形线圈内外的磁感应强度 。The relationship between the induced electric field and the current that sets up the field is deduced and applied to calculate the magnetic field from the current in windings of spherical shaped coils and to confirm the conclusion that the mutual inductances between any two coils are equal to each other.
