摘要
导出了导体环在一般交变磁场中的平均受力公式,以交变磁偶极子场为例讨论了导体环的受力方向,探讨受力大小与频率ω、导体环自感L等因素的关系.
The expression for mean force exerting on a conductor ring in alternating magnetic field is derived. The direction of the force in alternating magnetic field of magnetic dipole is discussed, and the relationships between the force and frequency to, the ring＇s self-inductance coefficient L are investigated.
