$8.$ A circular loop of flexible iron wire has an initial circumference of $160$ cm$,$ but its

circumference is decreasing at a constant rate of $11\mathrm{.}0$cm

s due to a tangential pull on the

wire. The loop is in a constant uniform magnetic field of magnitude $0\mathrm{.}900$ T$,$ which is

oriented perpendicular to the plane of the loop. Assume that you are facing the loop

and that the magnetic field points into the loop.

Find the magnitude of the emf induced in the loop after exactly time $2\mathrm{.}00$ s has passed

since the circumference of the loop started to decrease. What is its directio
