Electromagnetic Induction Flashcards
1
Q
Motional EMF
A
Separation of charges creates a uniform electric field within wire
2
Q
Faraday Law
A
EMF induced in a circuit = rate of change of magnetic flux through circuit
3
Q
Magnetic Flux
A
Measures density of magnetic field lines that cross through in an area
4
Q
Lenz’s Law
A
Induced current will always flow in direction that opposes the change in magnetic flux that produced it
