Problem

A single-turn rectangular coil of area

0.030\,\text{m}^{2}

is placed in a uniform

0.20\,\text{T}

magnetic field. Starting from rest with its plane perpendicular to the field at

t = 0

, the coil undergoes a constant angular acceleration of

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

. What is the magnitude of the induced emf at

t = 0.56\,\text{s}

? (a)

17\,\text{mV}

(b)

34\,\text{mV}

(c)

60\,\text{mV}

(d)

68\,\text{mV}
