In my revision guide it says, "flux linking is when emf is induced by changing the magnitude or direction of the magnetic flux."
I'm slightly confused here because earlier on the page it defines "flux linkage" as the total flux times the number of turns on a solenoid (so "flux linking" and "flux linkage" are different?), and in another book it defines "flux linking" as when magnetic field lines pass through an area (e.g. the cross-section of a coil) so the area is "linked" by the flux.
In other words, doesn't flux linking just mean when a magnetic field is passing through an area?
If someone can clarify how these three definitions are related, or if any of them are wrong, I would really appreciate it. My main concern is to know what flux linkage means in "real" physics because I am aware that revision guides tend to dumb down concepts a bit.
