U = L dI/dt
As the current increases, the energy is stored in inductor in form of magnetic field. This energy is then returned when current is falling.
XL = 2 π f L
Inductive reactance is strongly frequency dependent. For DC, inductor is short-circuit. The higher the signal frequency, the more inductor behaves as open circuit.
