This video tutorial shows us how we can build our own electric car using an AA battery, a pair of disc magnets and aluminum foil. It is so simple that it only circulates in a straight line, if you experiment with magnets you will see that it can take different directions. An ideal project to do with the little ones in the house. Its purpose is merely recreational and educational.

This project provides the two main ingredients of an electric motor: a flow of electric current and a strong magnetic field. The aluminum foil is conductive so it closes the circuit between the two poles and the battery, forming a magnetic field that makes the car move.
