Problem

A rigid rectangular loop of area

0.040\,\text{m}^2

is placed in a uniform magnetic field. At a certain instant the field magnitude is

0.25\,\text{T}

and is increasing at the rate of

0.020\,\text{T\,s}^{-1}

. The plane of the loop makes an angle of

60^{\circ}

with the field direction, and this angle is decreasing at

0.40\,\text{rad\,s}^{-1}

. Calculate the instantaneous induced emf in the loop at that instant.
