摘要
利用磁钢和硬币设计了操作简易的磁学演示实验,通过磁钢对铝镁合金制成的硬币的作用力的研究,有助于学生理解楞次定律.
Simple magnetism demonstration experiments using alnico and lauminium coin are designed. The active force that alnico adds on coins made from aluminum-magnesium alloy is analyzed. These demonstration experiments can help students to understand the Lenz law.
