Coil in high K powder

[Mark Ferris]

Does anyone know, or can speculate, what effect placing a solenoid
coil in a high K dielectric such as TiO2 powder would have upon the
generated composite field?

Does anyone know, or can speculate, what effect placing a solenoid
coil in a high K dielectric such as TiO2 powder would have upon the
generated composite field?

A coil in dielectric? Probably negligible, other than interwinding
capacitance, which could change the self-resonant frequency, but would
that change even be measurable?

Why not just try it? (I'm a techie, not an academician - I do hands-on
tests - when I've used only theory I've never gotten the right answer in
practice.)

Another possible consideration: what are the powder's magnetic
characteristics?

Cheers!

First speculate on the bulk K of the powder. Even though the individual
grains might be high K, I would bet the bulk K is not.
