用虚功原理讨论磁场对载流线圈的作用

Using Imaginary Work Principle to Discuss the Function of the Magnetic Field on the Carrier Coils

本文从虚功原理出发推导出任意形状载流线圈在外磁场中受力公式Ｆ＝１Φｍ，力矩公式Ｍ＝Ｉ＝，对均匀或非均匀磁场都能适用。

This paper, starting from the imaginary work principle, deduced bearing formula of any shape carrier coils under outer magnetic field F=IΦm, force moment formula suitable for both homogeneous and non - homogeneous magnetic fields.
