Polarized neutron scattering experiments under electric field in the commensurate phase of HoMnO and ErMnO have been performed to study the direct relation between the electric polarization and the magnetic chirality . It is found that, after cooling in electric fields down to temperatures where the system has both commensurate magnetic order and ferroelectricity, the magnetic chirality is proportional to the polarization.
