Suppose the first coil of wire illustrated in the simulation is wound around the iron core 6 times. suppose the second coil is wound around the core n2 = 12 times. shortly after the switch has been closed, the flux through the second coil of wire changes from 1.9 wb per turn to 2.4 wb in each turn of wire over a time interval of 0.2 s. find the magnitude of the emf induced in the coil.
