摘要
根据镜像原理和安培分子电流观点,推导了矩形磁块与一块大厚铁板之间的磁吸力的解析计算公式。用简单的实验证实了所得的计算公式可靠。
From the image method and molecular current viewpoint,an analytical calcultion formula about magnetic attractive force by rectangular permanent magnet on a large iron plate was derived. The reliability of the formula was confirmed with a simple experiment.
