When a coil is turned in constant magnetic field then maximum induced EMF is given by formula
now from above equation the maximum value is defined as
N = number of turns = 1
w = angular speed
A = area = 0.2* 0.2 = 0.04 m^2
B = magnetic field = 100 T
Now by above formula
So maximum value of induced EMF will be 25.13 Volts
