The behavior of water/oil/water double emulsion droplets with a cholesteric liquid crystalline middle phase (photonic microcapsules, PMCs) with magnetic nanoparticles ( m ‐PMCs) in a uniform magnetic field is demonstrated. The needle‐like aggregate of magnetic nanoparticles forms along the disclination line by the elastic interaction between particles and liquid crystalline director field. The m ‐PMC reorients in a uniform magnetic field.
