To solve this problem we will apply the concepts related to the electric field. This is defined as the product between the angular frequency, the number of turns of the body (solenoid in this case) the magnetic field and the sine of the angular frequency and time. Mathematically this can be described as
Here,
= Angular frequency
N = Number of turns
B = Magnetic field
The emf has its maximum value when
Thus the amplitude of the emf is
When number of turns of armature, area and applied magnetic field remains constant, induced emf is proportional to angular speed.
Further it can be written as follows,
Therefore the maximum amplitude of induced emf when armature rotates at 10.0rad/s is 18V
