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.   From the perspective of the magnet (i.e., pretend you’re the north pole of the magnet and are looking at the front of the solenoid), what is the direction of the induced current?    Counterclockwise      There is no induced current      One induced current is into the page, and the other is out of the page      Into the page      Clockwise
