Bob,
Mu Metal is quite often used in shielding applications. The
best description that I recall is that it soaks up the stray magnetic flux
passing near a closed region due to it large permeability. It makes sense
if you consider the total magnetic flux passing through a volume as
approximately constant but can be redirected. The Mu Metal is able to
perform the redirection function very well.
Essentially Mu Metal "internalizes" magnetic flux, static or changing. In so
doing, it heats up in the same way as a soft iron core of a transformer.
Almost no flux passes through. Plus the Curie point of Mu Metal is higher
than pure nickel and it is an order of magnitude more sensitive to flux than
soft iron (which is permeability).A cabinet which is covered in Mu Metal foil has zero field inside - from earth or anywhere else. No flux lines from a transformer placed on top of that cabinet would not be felt inside. The reverse is also true. If the LENR reaction, at any stage, involves hydrogen flipping rapidly from ortho to para alignment (THz) then that spin energy should be converted to heat by Mu Metal foil as both the electrode and flux sink. Frank Z yesterday states that nuclear spin orbit forces (or the magnetic moment of free electrons) are not conserved. This is something which I had not considered before, but if true, then this is another possibility for gain in LENR which is independent of a nuclear reaction. Note: the tritium reaction which occurs with deuterium (Claytor) could be the result of heat having been extracted instead of the cause of that heat. Thus, it could be possible to avoid that condition with hydrogen.
