Electromagnetic Induction Flashcards
1
Q
State Faraday’s Law
A
Faraday’s Law states that the magnitude of induced e.m.f is directly proportional to the rate of change of magnetic flux linkage (magnitude)
2
Q
State Lenz’s Law
A
Lenz’s Law states that the direction of induced e.m.f causes effect to oppose the change that produces it. (direction)

Q
Define magnetic flux
A
Magnetic flux through the surface is defined as the product of an area A and the component of the magnetic flux density B perpendicular to that area.
3
Q
Define magnetic flux linkage
A
Magnetic flux linkage through a coil is defined as the the product of the number of turns, N of the coil and the magnetic flux through each turn.
