Problem

A coil of

100

turns and area

0.010\,\text{m}^2

is placed in a uniform magnetic field of

0.20\,\text{T}

. The coil starts from rest and is set into rotation about an axis in its plane with a constant angular acceleration

10\,\text{rad s}^{-2}

. The plane of the coil is initially parallel to the magnetic field. Determine the magnitude of the induced emf in the coil at

t=0.50\,\text{s}

. a)

0.48\,\text{V}

1.9\,\text{V}

0.95\,\text{V}

0.32\,\text{V}
