电流环与磁偶极子等效变换中的磁荷计算

Calculation of Magnetic Charges in Equivalent Transformation Between Molecular Current and Magnetic Dipole

应用"磁荷观点"与"分子电流观点"在磁场计算中的等效性,计算了电流环与磁偶极子等效变换的量值关系.结果表明,一个半径为R,电流为I的电流环与一个"正负磁荷分别位于圆环两侧轴线,且距离环心各为±413R,磁荷量各为±4-13μ0πIR"的磁偶极子完全等效.分析指出,这种等效变换的适用条件是"磁荷可视为点磁荷".

Quantitative relation of equivalent transformation between molecular current and magnetic dipole is calculated based on the equivalence of magnetic charges ±4~-13)μ_0πIR and molecular current in electromagnetic field. It turns out that a circular current of radius R and current I is completely equivalent to a magnetic dipole with 'charges and each charge with a distance ±4~13)R away from the center of the circle , each charge is on the axis of the circle'. It is stated that the condition for holding the equivalent transformation is that a magnetic charge can be taken as a point magnetic charge.
