Calculaing Vortex Ring And Its Impedance
-
摘要: 本文将空心放置式线圈在平面异体中激发的涡流等效成一个环形涡流区域,计算该涡流环的尺寸,分析涡流环对检测线圈阻抗的影响以及计算涡流环的阻抗.Abstract: The eddy current generated by a empty coil on plane conductor is considered to be a clomain of vortex ring.The sige and impedance of the ring is calcalated,and the influence of the ring upon the impedance of the test coil is analysed.
