Jeff,
Some ferrite materials are design to change permeability with DC bias,
sometimes by as much as a factor of ten. I'm not sure if all mixes will do
this or only those specifically designed to do so.
I've been trying to come up with a useful application of this property for
Beverage matching, etc., but so far I can't think of how it could be used
to advantage.
