Re: Interesting inductor observation/phase of the moon?




http://www.ee.surrey.ac.uk/Workshop/advice/coils/terms.html
states the following;
If there is no ferromagnetic core so  mu, permeability
constant is 1.0 (the coil is 'air cored') then a
variety of formulae are available to estimate the
inductance. The correct one to use depends upon 

Whether the coil has more than one layer of turns. 
The ratio of coil length to coil diameter. 
The shape of the cross section of a multi-layer
winding. 
Whether the coil is wound on a circular, polygonal or
rectangular former. 
Whether the coil is open ended, or bent round into a
toroid. 
Whether the cross section of the wire is round or
rectangular, tubular or solid. 
The permeability of the wire. 
The frequency of operation. 
The phase of the moon, direction of the wind etc..
 
I wonder if this phase of the moon thing is a joke or
what? They seem to be serious*. HDN
