The peculiarities of magnetic field propagation in an anisotropic magnetic medium are considered and the dependences of the longitudinal and transverse components of the magnetic field on the geometric dimensions are established. For the first time, the possibility of concentrating the magnitude of the magnetic field has been shown and its value has been optimized. A model of an anisotropic magnetic concentrator is developed, and a method for creating artificial anisotropic classical materials is proposed. The application of this method of the magnetic field concentration makes it possible to increase the sensitivity of photo-, thermomagnetic detectors and the efficiency of galvano-thermomagnetic coolers, as well as electromagnetic and magnetoelectric measuring systems.
