as we know that the ohmic resistance of the inductor is very low.
when we apply some potential or voltages to the coil the coil energies and a flux is produced in it.
There are three types of effects when we apply voltages to the coil.
1) As according to the self induction when due to the change in direction or magnitude of flux then emf induces in that coil.
2) we know that when electricity is given to any motor than back emf induces in that motor so here back emf also produced and due to which a current also flows through the inductor which is opposite in direction to the supply current.this back current provides some resistance in the flow of current that's why current lags from voltage in inductors.
3) third and last one effect relates with the LENZ's law according to which current always opposes its own generating process.
so by the above given reasons we say that the current lags from the voltage in the inductor so the back current is partially stopped that current.
Due to that partial stop of current voltages become leading.
