Problem

A coil of 100 turns and area

0.05\,\text{m}^2

is rotated in a uniform magnetic field of

0.30\,\text{T}

and produces a peak emf of

300\,\text{V}

. Approximately what is the rotational speed of the coil in revolutions per minute? a)

3.8\times10^{3}\,\text{rpm}

1.9\times10^{3}\,\text{rpm}

9.5\times10^{2}\,\text{rpm}

2.7\times10^{3}\,\text{rpm}
