Breakdown of time-reversal invariance can be detected in macroscopic samples as a magnetic alignment along an electric field. We show that both fundamental and practical limits to the detection of this effect in paramagnets correspond to measurement of electron electric dipole moments down to de10-28ecm on 50-g quantities of EuS near its Curie point; this compares to the current limit of de<~10-24ecm. Strategies for still greater sensitivity are outlined.
