What you learn in Theory:
The EMF induced in a
loop is equal to rate of change of magnetic flux through that loop with respect
to time.
What you learn in Practice:
That whenever a
closed coil is placed under a varying magnetic field, a current will be induced
in the loop. The EMF can be calculated by differentiating flux with respect to
time. The flux can be varied by changing the magnetic field or by changing the
area of the loop.
