The magnetic field in a region is given by
B=2r, where
r is the perpendicular distance from the
x-axis. The direction of the magnetic field is along the positive
z -axis. A conducting rod of length
1 m lies parallel to the
y-axis as shown in the figure. If the rod moves with the velocity
v=8 m/s along the positive x-axis, find the emf induced between the ends of the rod.
