Move the wire through a magnetic field
Move a magnet through the coil of a wire |
Magnetic field lines must be cutting through the wire |
|
What is faradays law? |
The magnitude of the emf induced in a conductor equals the rate at which the conductor cuts a magnetic flux |
|
|
What is Lenz's law? |
The direction of the emf induced in a conductor is such that it opposes the change that produced it |
|
|
What does this equation and it's units represent? |
Size of the emf number of loops x change in magnetic flux ÷ change in time |
