Abstract: Numerical modelling of the rotation of a single-domain magnetic nanoparticle in the shell of a polyelectrolyte capsule under the action of a low-frequency magnetic field has been carried out. Was demonstrated the possibility of resonant increase of the rotation amplitude of magnetic nanoparticles in the studied system. From the modelling results it was determined that pulsed modes of exposure to low frequency magnetic field are more promising for controlled release of encapsulated substances.

Keywords: magnetic nanoparticles, polyelectrolyte capsules, low-frequency magnetic field, shell permeability control, pulsed magnetic field.
