Copper ring T V bar magnet N MOVES upward As the magnet moves toward the copper ring, the flux of the magnetic field through the ring increases from P1 to 2 during the time interval At. For the data below, what is the EMF around the ring while the magnet is in motion. DATA: $1 = 2.1 T m^2; $2 = 7.8 T m^2; At = 0.5 s. (in V)
