✔ 最佳答案
Keep住轉同一個方向都冇作為 = = D電線會繞埋一齊 ~ 之後到最尾會轉唔到 ~如果真係要整既話就要用一個 Electromagnet with varing current , 當佢一過左垂直個位
current in electromagnet 就轉方向 , B field 唔同左方向佢就會keep住轉 ~

當直流電摩打個換向器同電刷冇接觸之後發生咩事?
會慢慢地停下來唔轉。
如何整轉個個方向？
用你既手或其他機器拉佢轉。

the coil keep rotating and eventually stop
no connection bewteen carbon brush and commutator.
i.e no current
no magnetic force
no net force
Coil keep rotate due to inertia
