Problem

A rigid square loop is fixed in orientation such that the plane of the loop makes an angle of

30^{\circ}

with a uniform

0.25\,\text{T}

magnetic field. If the area of the loop is increasing at

3.0\,\text{cm}^2\!\!/\!\text{s}

, calculate the magnitude of the induced emf at this instant.
