N2 - In the presence of interactions which violate both P and T invariance, a ferroelectric crystal with electric polarization P and appreciable nuclear spin polarization, suspended in a magnetic field H, will experience a torque of the form P×H. The maximum torque density in PbTiO3 compatible with existing limits on such interactions is estimated at a few times 10-6 erg/cm3. Some obvious "nuisance" effects are estimated and the theoretical sensitivity of such an experiment discussed.
