某兴趣小组在研究扬声器结构时,发现扬声器中有一个环形磁体,他们不知道环形磁体的磁极分布情况,于是几位同学提出了以下三种猜想:猜想1:磁极呈横向分布(例如图甲,左侧为N极,右侧为S极)。
When one interest group studied the structure of a loudspeaker and found that there was a ring magnet in the loudspeaker and they did not know the magnetic pole distribution of the ring magnet, several students put forward the following three conjectures: Conjecture 1: The magnetic poles are transversely distributed (for example, N pole on the left and S pole on the right).
