That's a nice detailed explanation of inductors. Although I snipped it due to text length. At any moment in time may know how much energy a pure inductance is consuming from the source or adding to the source by multiply V * I. During the first half cycle of a sine wave the inductor consumes energy. During the last half of the cycle the inductor returns the energy. Thus, the reason current and voltage are 90 degrees out of phase in a pure inductor.
