Do you know how to read?

to your statement that quartz has no electrical or magnetic effects?

Here's what I actually said:

Since crystals aren't electrically conductive to any degree and have no permeability to speak of, their effects with regard to H-field interference will be virtually nill.

Just wondering,. because I can find reference in a standard electrical engineering text about the magnetic properties of all materials, but you have stated that quartz can have no affect at all.

Great. Then get out your "standard electrical engineering text" and tell us what the relative permeability of quartz is.

Because I have several myself as well as texts specifically relating to the electrical properties of materials. None of them give the relative permeability of quartz. Nor do any Google searches turn up anything.

Here's why.

Quartz is diamagnetic.

However the most diamagnetic material outside of a superconductor is bismuth. And even then bismuth is only VERY VERY weakly diamagnetic. For all intents and purposes, it's about as effective as air at shielding from magnetic fields, save for eddy current losses due to the fact that bismuth is a conductor rather than an insulator as quartz is.

So as I said, their effects as far as H-field interference goes is virtually nill.
