In electrical engineering the term flux linkage is used to define the interaction of a multi-turn inductor with the magnetic flux as described by the Faraday's law of induction. Since the contributions of all turns in the coil add up, in the over-simplified situation of the same flux passing through all the turns, the flux linkage (also known as flux linked) is , where is the number of turns.[1] The physical limitations of the coil and the configuration of the magnetic field make some flux to leak between the turns of the coil, forming the leakage flux[2] and reducing the linkage. The flux linkage is measured in webers (Wb), like the flux itself.
