Problem

A square loop of

50

turns, side decreasing uniformly from

0.50\,\text{m}

0.20\,\text{m}

0.050\,\text{s}

, lies perpendicular to a uniform

0.80\,\text{T}

magnetic field. The loop is made of wire whose total resistance is

2\,\Omega

. Assuming the rate of change of area is uniform, the heat produced in the loop during this interval is closest to (a)

353\,\text{J}

(b)

706\,\text{J}

(c)

282\,\text{J}

(d)

1411\,\text{J}
