Make A Simplest Electric Motor At Home
I will show you how to create a simple homopolar electric motor here. It’s really easy to do, and you will not need any professional material or stuff to do that at home. Today, I will design a simple one, you can also create your own homopolar motor with some creative design.
Safety Tips
