The World's Simplest Motor
Students create a simple motor using an electromagnet.
In this activity, students see how an electric current running through a coiled wire creates a magnetic field. Two magnetic fields, repelling and attracting each other, can be used to convert the electrical energy of the battery into the mechanical energy of a spinning part.
This activity can take 20 minutes (including discussion) as a demonstration, or 45 minutes or more if students make one themselves.
Students will be able to:
- Describe the effect of applying electricity to a magnetic object.
