Electromagnetic Induction Flashcards
1
Q
ELectromagnetic Induction
A
The production of an electric current across a conductor moving through a magnetic field.
2
Q
Induced emf (or current)
A
Produced by a magnet (or a coil) relative to a magnetic field.
3
Q
Lenz’s Law
A
The direction of the induced current is always so as to opposed the change which causes the current.
4
Q
Magnetic Flux
A
The total number of magnetic field lines passing through a specified area in a magnetic field.
5
Q
Faraday’s Law of Electromagnetic Induction
A
The induced emf in a circuit is equal to the rate of change of flux linkage through the circuit.
