课题介绍
Place a non-ferromagnetic metal disk over an electromagnet powered by an AC supply. The disk will be repelled, but not rotated. However, if a non-ferromagnetic metal sheet is partially inserted between the electromagnet and the disk, the disk will rotate. Investigate the phenomenon.
将一个非铁磁性的金属碟放在通交流电的电磁铁上,金属碟会排斥但不会旋转。但如果一块非铁磁性的金属薄片被部分插入两者之间,金属碟会旋转。研究这个现象。
