Physic project -- DC motor with electromagnets

AI Thread Summary
The discussion focuses on building a DC motor using four electromagnets instead of permanent magnets. Participants suggest starting with YouTube tutorials, emphasizing the need for electromagnets to replace traditional magnets. One contributor recalls a Tin Can Motor that utilized two electromagnets, highlighting the possibility of using electromagnets in the design. It is noted that while one electromagnet can be continuously powered, the others must be activated alternately and in sync with the motor's rotation. The conversation underscores the feasibility of using electromagnets in place of permanent magnets for the project.

Thanks but my teacher do not want magnet. He wants it to be electromagnets instead. I'm a bit a t lost here. Do the electromagnet ca replace the magnet?
 
I built, what was called a Tin Can Motor, when I was a kid. It used a coil on the rotor (moving part) and the stator (stationary part). So it had 2 electromagnets, rather than any permanent magnets. Here is a link that I found to some vintage projects, which are not exactly that, but similar. I am not sure about if there are 4 electromagnets, or not. http://www.vintageprojects.com/science/5-motors.pdf

Yes. One electromagnet will be permanently excited in one current direction but the other you will have to figure out how to excite it alternately and synchronously with the rotation of the motor ...
 
Here is another one that I found, you may find interesting.
 
If you see a simple motor built around a horse-shoe permanent magnet, then you can replace that horse-shoe magnet with a similarly-shaped electromagnet.
