Electromagnetic Induction and Faraday's Law

These flashcards cover key vocabulary terms and concepts related to electromagnetic induction and the laws governing the behavior of electric and magnetic fields.

Faraday's Law

States that a change in magnetic flux through a circuit induces an electromotive force (EMF) in that circuit.

Induced EMF

An electromotive force generated in a circuit due to a change in magnetic flux.

Magnetic Flux (Φ)

The product of the average magnetic field times the perpendicular area that it penetrates.

Lenz's Law

States that the direction of induced current is such that it opposes the change in magnetic flux that produced it.

Motional EMF

The EMF generated when a conductor moves through a magnetic field.

Maxwell's Equations

A set of four equations that describe how electric and magnetic fields interact.

Coil with N turns

A loop of wire wound into a coil shape, with N representing the number of turns of wire.

Ampère's Law

Relates the integrated magnetic field around a closed loop to the electric current passing through the loop.
