A slinky with N even loops of area A is L long. You hook it up to a circuit and increase the current at a rate of 2.0 A/s, and measure an induced EMF of 75 mV. What is the slinky's inductance? Now take the ends of the slinky and pull them out so it's 2L long. Will this change the induced EMF, and if so, explain how? Now calculate the new induced EMF.
