4.4/5 magnets Flashcards
1
Q
What is Hall voltage?
A
When a magnetic field is applied to a conductor with a current, at right angle to field direction, voltage is perpendicular to B and I
2
Q
What is Faraday’s law?
A
When flux linking an electrical circuit is changing, an emf is induced in the circuit of magnitude equal to rate of change in flux linkage
3
Q
What is Lenz’s law?
A
The direction of any current resulting from induced emf will oppose change in flux linkage
