Consider a 12-loop coil with a diameter of 8 cm; a north-leading bar magnet moves further away from the coil (where the bar magnet is perpendicular to the cross section of the coil, and the north pole is closest to the coil as the magnet moves away). The magnetic field value changes from 0.065 T to 0.00065 T in 1.6 s.   What is the induced emf for the coil?  emf =    V
