[Boatanchors] Why L?

[Rod Hogg]

Dan...et al..

You hit the reasoning on the head, according to my source.

>From McGraw-Hill Book, "A Course in Electrical Engineering"  Vol 1,
by Chester Dawes, S.B., A.M. of Harvard and IEE , Dated -1937-.
Chapter IX, Self and Mutual Inductance....

"......the fact that a current and the flux which it produces always
completely encircle each other. Hence, they are said to -link- each
other.  The mutual linking action is particularly well illustrated
.......

"The product of the turns of a conductor and the number of lines of 
flux linking these turns is called the -flux linkages- of the circuit.
These linkages will be given in c.g.s. units if the flux is given
in maxwells.

"When the reluctance of the magnetic circuit is constant, the number 
of these linkages per unit current is call the -self-inductance- of 
just the -inductance- of the circuit and the represented by the 
symbol "L", implying linkages.   The unit of inductance is the henry."

I hope this was appropriate to quote this.  Makes for good brain food
to read through the old texts now and then.
