It's a bit superficial for high school students to do that. . This is something done by elementary school students. . . Unless you have really innovative ideas.
Let me give you some advice.
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 costs only about ten yuan. If you really want to make it yourself, you must first buy one and take it apart to study it.
2. Do not use alternating current. Two poles are enough to make a small electric bead shine.
3. If you throw it by hand, use a gear to change the speed. Otherwise, even if you shake your hand, it won't have much effect.
I wish you good luck
