Assume we have this circuit:
At t=0s we decide to close the switch, then current will start flowing through the circuit and around the inductor a magnetic field will be induced.
My questions: According to Faraday's law, the electric voltage generated on a coil will depend on the change of the magnetic flux through the coil. Since the magnetic field grows at a constant rate shouldn't the back emf of the inductor remain the same? Why does it have the form it does?
