It's a bit superficial for high school students to do this. . This is something made by primary school students. . . Unless you have some really innovative ideas.
Let me give you some tips.
1. The rotor must be balanced. If you make it yourself, you must use silicon steel sheets. It is recommended to buy a motor, which only costs about ten yuan. If you really want to make it yourself, you should buy one first and take it apart to study it.
2. Don’t use alternating current. Two poles are enough to make a small electric bead shine.
3. If you crank it by hand, use a gear to change the speed. Otherwise, even if you shake the hand off, it won't have much effect.
Wish you good luck
