Why Lesson Planet?
Instructions for building a simple electromagnetic motor are provided for the teacher. Aside from some sketchy background information and a list of content standards to be met, that is about all you will find in this resource. The motor is a nifty one, but note that directions do not tell how to secure the magnets to the cup. Also, there are no explanations of why this works. If you know the concepts and can explain them, then this is a neat demonstration to do for upper elementary or middle school physical science classes.
