Ck 12: Electromotive Force
[Free Registration/Login may be required to access all resource tools.] Explains what electromotive force, or EMF, is, and how to calculate the EMF of a moving wire in a magnetic field.
Exploratorium
Exploratorium: Science Snacks: Motor Effect
"A magnet exerts a force on current-carrying wire." This simple device shows how magnets affect wires with current in them, the basis of the electric motor. If you see, feel and understand this, the electric motor becomes very clear.
