A simple pendulum length \( l \), made of conducting material swings with small amplitude \( \theta_{0} \) in a uniform magnetic field of magnetic induction \( B \). Plot the voltage induced in the pendulum if the magnetic field is perpendicular to the plane of oscillation. At \( t=0 \), the string is vertical.
