Q
Explain the ‘motor effect’ in relation to electromagnetism.
A
The motor effect is the term used when a current-carrying wire in the presence of a magnetic field experiences a force. A simple experimental demonstration will show you that this is true. Place a wire that is connected to a power pack in between the poles of a horseshoe magnet.

Q
Describe a hand rule or palm rule that will allow you to determine the direction of the force on a current-carrying conductor in a magnetic field.
A
