[TCML] Magnetic flux

[Ken Herrick <kchdlh@xxxxxxxxx>]

Greetings to the List after a long hiatus for misc. reasons (death of 
wife, new ladyfriend, making art, old age).  I find this definition of 
magnetic flux on-line:  "Magnetic flux is the product of the average 
magnetic field times the perpendicular area that it penetrates. It is a 
quantity of convenience in the statement of Faraday's Law and in the 
discussion of objects like transformers and solenoids. In the case of an 
electric generator where the magnetic field penetrates a rotating coil, 
the area used in defining the flux is the projection of the coil area 
onto the plane perpendicular to the magnetic field."   So while 
currently attempting a resuscitation (yet again) of my 1-&-only coil, it 
occurs to me to ask (perhaps already answered here) whether confining 
the secondary's magnetic flux, within the secondary and annularly to a 
volume closest to the wire, would have any beneficial effect.  Anyone know?

One might be able to so confine the flux by arraying a stack of 
conductive disks centrally within the secondary, but spaced and 
electrically isolated one from the other.  Eddy currents in the disks 
would deflect the flux into the annular volume nearest to the wire.

Since I don't regularly, for now, inspect the List all the time, anyone 
responding to this might kindly copy to me at 
kchdlh---at---sonic--dot--net using the customary format, of course.
