The presence of a magnetic toroidic dipole moment T in condensed matter is due to the presence of a magnetoelectric effect : Application of a magnetic field H in the plane of a toroidal solenoid leads via the Lorentz force to an accumulation of current loops and thus to an electric polarization perpendicular to both T and H. The resulting polarization has the form P i = ε ijk T j H k (with ε being the Levi-Civita symbol). The resulting magnetoelectric tensor describing the cross-correlated response is thus antisymmetric.
