The Electric motor challenge!

*** Please don't try to use this motor for anything practical! It is really weak :D ***

You are hearby challenged to make an electric motor! :D

UPDATE: I added a inner core without any iron for the electromagnet, there is no point to use a metalcore if the electromagnet cant overcome the attraction anyway. For an electromagnet with air core, the internet suggests a tall and thin windig of the wire since the "magnetic field" cant travel along the length of an air core. Thas why I have a very thin gap for the wire. This setup actually used a bit less power. 0.6- 0.8A instead of 0.9A. The air-core electcromagnets truly is very weak, so be sure to make a close design for your parts.

As a kid, I discovered an electric motor entirely made in acrylic glass, It was on display on a small table in a closed room in a friends family house. It was a large transparent disk with metalfoil attached to it - wires here
