A long straight (line) conductor carries a current i that increases
at a rate di/dt. Below this current-carrying conductor is a rectangular
conductor as shown in the figure below. Given that a/b = 4 and assuming
that the dimensions of the rectangular conductor are small enough to
experience an almost instantaneous change in the magnetic field due to
the current change in the long current-carrying conductor above it, what
is the magnitude of the induced emf in the rectangular conductor?
