Describe electromagnetic induction.
Generating an electromotive force (emf) or voltage across a conductor when it is exposed to a changing magnetic field.
Causing a decrease in the resistance of a conductor
Creating a static magnetic field around a conductor

State Faraday's law of electromagnetic induction.
The induced EMF in a circuit is equal to the magnetic flux through the circuit.
The induced electromotive force (EMF) in any closed circuit is equal to the rate of change of the magnetic flux through the circuit.
The induced EMF in a circuit is inversely proportional to the rate of change of magnetic flux.
The induced EMF in a circuit is directly proportional to the resistance of the circuit.
