| 摘 要： | 从磁偶极子的特点出发，用毕奥一萨伐尔定律、安培力公式和力矩的定义，推导出用磁矩表示的矩形载流线圈沿一中线折成直角的远场及其在均匀磁场中所受的磁力和磁力矩，指出此非平面载流线圈可看作磁偶极子．

| Abstract: | By using the Boit - Savart law, Ampere force formula and the definition of moment of force, the paper deduces, on the basis of the characteristics of magnetic dipole, not only the far field which is made by folding the rectangle current coil showed in magnetic moment along the median in right angle, but also the magnetic force and its moment which the far field stands in the uniform magnetic field. It also points out that such a nonplanar current loop can be regardedas magnetic dipole. |
