a) The max emf obtained in a rotating coil of N turns is given by:
where N is the number of turns in the coil, B is the magnitude of the magnetic field, A is the area and w is the angular velocity of the coil.
By calculating A and replacing in the formula (1G=10^{-4}T) we get:
Finally, the peak current is given by:
b)
we have that
