of 180 cm2 is made of 210 turns
of copper wire (shown in the figure below). The wire making up the
coil has no resistance; the ends of the wire are connected across
a 3.00-Ω resistor to form a closed circuit. Initially,
a 1.40-T uniform magnetic field points perpendicularly
upward through the plane of the coil. The direction of the field
then reverses so that the final magnetic field has a magnitude
of 1.40 T and points downward through the coil. If
the time interval required for the field to reverse directions
is 0.400 s, what is the average current in the coil
during that time?
