In classical electrodynamics, the dynamic toroidal dipole arises from time-dependent currents flowing along the poloidal direction on the surface of a torus. In relativistic quantum mechanics, spin contributions to the toroidal dipole needs to be taken into account. Toroidal dipole moments are odd under parity and time-reversal symmetries. Dynamic toroidal dipole is distinguished from the static toroidal dipole introduced by Zeldovich in 1957 under the name of static anapole.
