If ferromagnetic materials are located near the conductor, such as in an inductor with a magnetic core, the constant inductance equation above is only valid for linear regions of the magnetic flux, at currents below the level at which the ferromagnetic material saturates, where the inductance is approximately constant. The input impedance of the network is given by, For Any alteration to a circuit which increases the flux (total magnetic field) through the circuit produced by a given current increases the inductance, because inductance is also equal to the ratio of magnetic flux to current[12][13][14][15]. The resonant frequency of the series RLC circuit, f = 1 / [2 (L C)], depends on the inductance of the inductor L and the capacitance of the capacitor C.
