Recently it was pointed out that, in the same way that electric polarisation can be generated by spatially varying magnetic order, magnetism can be generated by a temporally varying polarisation. The resulting phenomenon was called Dynamical Multiferroicity. The magnetisation,  is given by
where  is the polarisation and the  indicates the vector product. The dynamical multiferroicity formalism underlies the following diverse range of phenomena:
* The phonon Zeeman effect, in which phonons of opposite circular polarisation have different energies in a magnetic field. This phenomenon awaits experimental verification.
* Resonant magnon excitation by optical driven phonons.
* Dzylaoshinskii-Moriya-type electromagnons.
* The inverse Faraday effect.
* Exotic flavours of quantum criticality.
