Question:medium
A square loop of side 2 cm makes angle 60° with magnetic field \( \mathbf{B} = 0.4 \sin(300t) \, T \). Find maximum induced EMF (in mV) in loop.
A square loop of side 2 cm makes angle 60° with magnetic field \( \mathbf{B} = 0.4 \sin(300t) \, T \). Find maximum induced EMF (in mV) in loop.
Show Hint
To find the maximum induced EMF, differentiate the magnetic flux with respect to time and use the fact that the maximum value of the cosine function is 1.
