Flux Linkage and Current

Graph showing how the flux linkage varies with current

The "flux linkage" in an inductor is proportional to the applied current and the inductance of the inductor. Thus:

N Φ = L I

where Φ is the flux (in Webers), N is the number of turns, L is the inductance (in Henries), and I is the current (in Amperes).
