Post Electromagnetic Induction

Define the term electromagnetic induction.

• Production of voltage in a wire due its interaction with a magnetic field

• A force applied to a magnet that is induced by a changing current in a nearby wire

• Turning a non-magnetic material into an electromagnet

• Current produced by a supplied voltage.

Explain how you can create an induced voltage in a wire.

• Place it in a changing magnetic field.

• Move it through a magnetic field.

• Place it in a constant magnetic field.

• Use a force.

Explain what the electromotive force is.

• Force that pushes electrons through the circuit.

• Current that was induced in the circuit.

• Force used to push the magnet near the wire.

• Voltage that was induced in the wire.

Recall what would happen if you quickly changed the magnetic field surrounding a loop of wire.

• A small current would be induced in the loop

• A large current would be induced in the loop.

• There would be no induced current.

Recall what would happen if you slowly changed the magnetic field surrounding a loop of wire.

• A small current would be induced in the loop

• A large current would be induced in the loop.

• There would be no induced current.
