摘　　要：根据楞次定律的另一种表达说明了导电颗粒因有涡电流而受原磁场的磁力是在过导电颗粒的圆周(圆心在磁辊轴心)的切线方向,指向磁辊转动的前方,并举例说明了这种说法与试验现象吻合。说明了关于“涡电流力是排斥力”的说法的论据不够充分,举例说明了关于“涡电流力是排斥力”的说法与试验现象相悖。In accordance with the Heinrich Friedrich Lenz Law,it is presented that the direction of the eddy current force is tangent line direction of the circumference,that it pass the metallic particle and its center locates on the center of the magnetic roller.It is illustrated that this statement is identical with the experiment phenomena.It is presented that the argument on the statement about that,eddy current force is the repellent force,is insufficient.It is illustrated that the statement about that,eddy current force is the repellent force,is inconsistent with experiment phenomena.
