The dynamic magnetic susceptibility of rotating magnetic fluid in transverse magnetic biasing field

Theoretical examination of influence of non-linear magneto-vortical interaction in the magnetic colloid rotating in a traversal field on its axial (along a spin axis) dynamic magnetic susceptibility are presented. The mechanism of the phenomenon of the magneto-vortical resonance consisting in occurrence of a maximum on dependence of an axial susceptibility from a rotation frequency near to frequency of the measuring field registered in experiments is shown.
