You have a coil with 20 loops inside a magnetic field generator that is temporarily generating a field that has a rate of change of -0.25. The other end of this coil is wrapped around a core with 15 turns. How many turns must a second coil wrapped around the same coil have to produce an output voltage of 25 V?
