涡流分选方法及其应用魏以和（武汉化工学院）１涡流分选方法的基本原理［１－４］根据电磁感应定律，当穿过导体的磁通量发生变化时，在导体中就会产生感应电流。如果导体为块状，则块体中的这种感应电流就会呈涡旋状，称之为电涡流，简称涡流。涡流是感生电流，遵从楞次...
Eddy current sorting method and its application Wei and (Edited by Weihe Wei) 1 The basic principle of eddy current sorting method [1-4] According to the law of electromagnetic induction, when the magnetic flux through the conductor changes, there will be induction in the conductor Current. If the conductor is massive, then the induced current in the block will be vortex, called eddy current, referred to as eddy current. Eddy current is induced current, follow Lenz ...
