F5C4: Electromagnetism Flashcards
1
Q
magnetic field
A
a region where a magnetic material experiences a magnetic force
2
Q
electromagnetic induction
A
production of an induced e.m.f in a conductor when there is relative motion between the conductor and a magnetic field
3
Q
Lenz’s Law
A
the direction of induced current is such that the change producing it will be opposed
4
Q
Faraday’s Law
A
magnitude of the induced current is directly proportional to the rate of change of magnetic flux
