EM Induction Flashcards
1
Q
What is generated in a solenoid?
A
A magnetic field
2
Q
What direction does current flow at the north pole in a solenoid?
A
Current passes aNticlockwise at the North pole.
3
Q
What is Lenz’s law?
A
The direction of induced current is always such as to oppose the change that causes the current.
4
Q
What hand does one use when a current is induced from a moving magnetic field?
A
The right hand. This is known as the dynamo rule.
5
Q
What is 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.
