Abstract
A continuum theory is presented for the cholesteric liquid crystals subject to electromagnetic interactions. Complete field equations, jump conditions and constitutive equations are obtained. Constitutive equations include all first and second degree effects some of which are new. These include the curvature piezomagnetism, electrostrictive and magnetostrictive couples, magnetization due to motion, etc. The thermodynamic restrictions and other invariance requirements are studied. The field equations are employed to study the effect of the magnetic field on the reorientation of the molecules and transition to nematic state.
