摘要
导体棒旋转切割磁感线问题在近几年高考中不断出现.在微分思想下使用微元图像结合法解决导体棒速度与长度乘积问题,以微元图像法和有效长度法两种方式解决旋转切割产生电动势的系列问题,创新提出并解决曲线导体棒旋转切割问题.
In recent years,the problem of conductor rod rotating cutting magnetic induction line appears constantly in college entrance examination.In this paper,the product problem of conductor rod speed and length is solved by using the combination method of micro-element image,and the series problems of electromotive force generated by rotary cutting are solved by using the method of micro-element image and the method of effective length.The rotary cutting problem of curved conductor rod is proposed and solved creatively.
