Key Questions:

1. What is the basis of an electric motor?
   • A coil of wire carrying a current in a magnetic field tends to rotate. This is the basis of an electric motor.
2. How does the force on a conductor in a magnetic field causes the rotation of the coil in an electric motor?
   • A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a Force and moves. One side moves up and the other side moves down (based on Fleming's left hand rule).
