Eli and Baraz decide to do the following problem from the book. If a coil consists of N turns with the same area and is the magnetic flux through one coil, an emf is induced in every coil. The coils are in series, so their emfs add; therefore, the total induced emf in ΔΦ the coil is given by E = -N- -NAⓇ At Suppose the first coil of wire illustrated in the simulation is wound around the iron core 7 times. Suppose the second coil is wound around the core N₂ = 18 times. Shortly after the switch has been closed, the flux through the second coil of wire changes from 3.0 Wb per turn to 3.5 Wb in each turn of wire over a time interval of 0.3 s. Find the magnitude of the emf induced in the coil. BV
