Hi, we have been doing lots of work recently on magnets. we have learnt about the ideas of flux, and using them to describe induction and how transformers work etc. i feel that i understand quite well about these ideas, but now i have come across this idea of 'flux linkage'. i do not understand what this is. the definitions i have been reading don't seem very explicit. so please can somebody explain to me what it is, and why the ideas are important/useful. thanks in advance.
