... If a single flux passes through a coil, the coil is ‘linked’ to the flux (or ‘threaded’ by the flux). We could say there is magnetic flux linkage of 1. If the coil is linked (‘threaded’) by two flux then the flux linkage is 2 and so on. Increasing the number of coils also increases the flux linkage ...
