FIELD: magnetic fields.
SUBSTANCE: method for controlling the structure of strong magnetic fields in meso-sized dielectric spherical particles includes manufacturing a spherical dielectric particle from a transparent material for the radiation used and with a meso-sized diameter, irradiating a spherical dielectric particle with generated monochromatic radiation, excitation of high-order superresonant Mie modes in the spherical particle and forming optical vortices inside the spherical dielectric particle with the formation of hot spots around the poles of the spherical particle along the direction of radiation propagation, whereas according to the invention, the dielectric spherical isotropic particle is rotated, the irradiation of the rotating dielectric spherical isotropic particle is carried out with monochromatic radiation with a plane wave, whereas the rotation speed of the dielectric spherical isotropic particle rotating around its optical axis is perpendicular to the plane wave of monochromatic radiation incident on it, which ensures the formation of an asymmetric distribution of the magnetic field.
EFFECT: ability to control the shape and intensity of strong magnetic fields in mesosized dielectric spherical particles.
