Explanation:
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

Answer:
Explanation:
Given
mass of disk
diameter of disc
Force applied
Now this force will Produce a torque of magnitude
And Torque is given Product of moment of inertia and angular acceleration
Moment of inertia for Disc
