eddy current quartz

Can quartz crystals create eddy currents when exposed to ...

Answer (1 of 2): NO, unless they are doped with impurities, in the same manner of semiconductors, which is very unlikely to be doable. Quartz crystal is the crystalline form of silicon dioxide - SiO2 (sand), thus it’s not a conductor. Eddie currents (Foucault currents) are inducted on conductors...
