Problem

A coil of 100 turns, each of area

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

, rotates with an angular speed of

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

in a uniform magnetic field of

0.15\,\text{T}

. The normal to the coil makes an angle of

60^{\circ}

with the field at

t=0

. Determine the induced emf at

t = 2.0\times10^{-3}\,\text{s}
