text: This induced current acts to keep the current flowing in the coil; the induced current opposes any change, an increase or a decrease, in the current through the inductor.
text: This is because a voltage is being applied to the circuit and little or no current is flowing because L is effectively (for a very short time) a very high resistance due to the back EMF effect caused by the rapidly changing (expanding) magnetic field around the inductor inducing a voltage (a back EMF) back into the inductor, which is in opposite polarity to the applied voltage from the supply, and so initially opposes the increase in current through the inductor.
