A simple pendulum made of mass $\displaystyle 10$ g and a metallic wire of length $\displaystyle 10$ cm is suspended vertically in a uniform magnetic field of $\displaystyle 2$ T. The magnetic field direction is perpendicular to the plane of oscillations of the pendulum. If the pendulum is released from an angle of $\displaystyle 60$° with vertical, then maximum induced EMF between the point of suspension and point of oscillation is
$\displaystyle \_\_\_\_$ mV. (Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
