A coil of

50

tightly wound turns encloses a fixed area of

2.0\times10^{-3}\,\text{m}^2

. It is oriented so that its area vector is parallel to a time-dependent magnetic field given by

B(t)=0.30\sin(120\pi t)\,\text{T}

, where

t

is in seconds. Determine the instantaneous induced emf in the coil at

t=2.0\times10^{-2}\,\text{s}
