Subject: RE: The Poynting vector, wire length and  inductance (fwd)

It has been known for longer than any of us have been  around that the
inductance of a solenoid is proportional to the number of  turns,
squared.  As the wire length is proportional to the number of  turns, it
follows that the inductance is also proportional to the wire  length,
squared.  Is this the extent of the point that you were trying  to make?
I see nothing new here and don't see the need to drag calculus  and
Poynting vectors into this.
