The Villari effect is the magnetic equivalent of this effect, while a Joule effect that has nothing to do with heating is the magnetic equivalent of its converse.  
The Villari effect is the magnetic equivalent of this effect, while a Joule effect that has nothing to do with heating is the magnetic equivalent of its converse.  Coefficients associated with it can be measured with a device named after Berlincourt.  This effect is widely utilized in (*) polyvinylidene fluoride, or PVDF, and along with EMA probes, materials exhibiting it are used to generate Lamb waves.  A "balance" based on this effect was the subject of Jacques Curie's doctoral thesis.  It only occurs in materials whose crystal lattices lack center symmetry.  For 10 points, name this effect in which mechanical stress produces a voltage difference, most commonly observed in quartz.
