The paper studies the convective stability of the stratified by magnetophoresis and thermal diffusion ferrofluid, placed in a heated from its narrow face Hele-Shaw cell. The cell is subjected to a nonuniform magnetic field with a modulated contribution. The characteristics of parametric instability are obtained, and depicted in the graphs of the dependence of critical magnetic Rayleigh numbers on the amplitude and inverse frequency of external modulation. The types of emerging flows are described and their evolution over time is presented. Keywords: ferrofluid, magnetophoresis, thermal diffusion, Hele-Shaw cell, parametric resonance.
