Problem

A coil of 150 turns, each of area

2.0 \times 10^{-3}\,\text{m}^2

, is rotated at a constant angular speed of

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

about an axis perpendicular to a uniform magnetic field of

0.30\,\text{T}

. The plane of the coil is perpendicular to the field at

t = 0

. Find the instantaneous emf induced in the coil at

t = 2.0 \times 10^{-3}\,\text{s}
