... 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 ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
