Suppose the first coil of wire illustrated in the simulation is wound around the iron core 9 times. Suppose the second coil is wound around the core N2 = 20 times. Shortly after the switch has been closed, the flux through the second coil of wire changes from 1.9 Wb per turn to 2.6 Wb in each turn of wire over a time interval of 0.3 s. Find the magnitude of the emf induced in the coil.
