I have to agree Frank, the fundamental reason why a wire has inductance is a

Let's hope that any 'colloquialisms' or 'idiomatic expressions' are
suitably flagged, as some people appear to believe that such
statements count as fundamental science and carry on into a form of
adulthood still using them but without any further thought.

Makes you wonder about degrees from the UoE, does it not?

I believe it was claimed to be 'avant-garde' at the time - possibly
the sort of environment where lecturers sent off the students to
research things for themselves, after giving a few pointers, rather
than just writing it all on the board.

Some can cope with this, and some can't.....rather in the manner of
those who must wait for the outcome of an inquiry to tell them what
officially happened, rather than working out the various scenaria for
themselves.
