A rectangle measuring 30.0 {rm cm} by 40.0 {rm cm} is located inside a region of a spatially uniform magnetic field of 1.30 T, with the field perpendicular to the plane of the coil (the figure ). The coil is pulled out at a steady rate of 2.00 {rm{ cm/s}} traveling perpendicular to the field lines. The region of the field ends abruptly as shown.
Find the emf induced in this coil when it is all inside the field.
