Problem
A square loop of side 0.20 m remains centered in a uniform magnetic field of constant magnitude 0.20 T. Initially the loop’s area vector is parallel to the field, but the loop begins rotating about one of its edges at a constant rate of 15° s⁻¹. Calculate the magnitude of the induced emf in the loop exactly 2.0 s after the rotation begins.
