FIELD: biophysics.
SUBSTANCE: invention relates to biophysics and can be used to create biomedical sensors and micromanipulators. Method of manipulating magnetic nano- and micro-objects includes generating an alternating magnetic field, capturing, holding and moving ferromagnetic particles and/or magnetically marked biological objects using an alternating magnetic field and controlling the position of particles using video microscopy, is characterized by that the formation of the alternating magnetic field is carried out by irradiating the formed monochromatic coherent radiation of a spherical dielectric particle made from a transparent material for the radiation used with a mesoscale diameter, exciting high-order super-resonant Mie modes in the particle and forming hot spots around the poles of the spherical particle along the direction of propagation of radiation with intensity of the magnetic field exceeding the intensity of the electric field in them.
EFFECT: reduced dimensions of the magnetic field source and formation of a magnetic field in the subwavelength region of space.
