When an AC source is connected with an inductor we have a continuous change in voltage and current across the inductor.

According to Farady and Lenz law we will get an equal and opposite voltage against the source voltage for each change of voltage or current across the inductor. 

Now since we always get an equal and opposite voltage across the inductor for each change in source voltage so it means that the current will never be able to flow in the inductor but yet current is always flowing in each text book. I am confused about it. Please guide me. I shall be grateful to you. Note that it is an ideal case and we have no resistance in the circuit.
