《电流间相互作用》是一个选做的演示实验,《高中物理实验大全》对这个演示实验介绍了五种演示方法,现再补充一种材料易找、制作简单、效果好的自制教具。1 制作方法 1.如图1所示的附有底座的木质框架。 2.方形线圈2个;小型接线柱4个;大型接线柱2个;双刀双掷开关1个;导线若干。
“Current interactions” is an optional demo experiment. “High School Physics Experiment Encyclopedia” introduces five demonstration methods for this demo experiment. Now it adds a self-made teaching aid with easy-to-find materials, simple production and good results. 1 Production method 1. As shown in Figure 1 with a wooden frame of the base. 2. Two square coils; four small terminal posts; two large terminal posts; one double-pole double-throw switch;
