We have investigated the distribution of constant magnetic field on the surface of the magnetic nozzle (in-cluding the area of the optical radiation) in the apparatus for magneto-laser therapy, and developed me-thods for correcting the magnetic induction. It is shown that for the widely used in medical practice apparatus, having an expressed therapeutic effect because of the synergy of these physical factors, the magnetic induction in the area of the optical radiation is 3,5-4,0 times less than its value over the pro-jection of the body of the commonly used in such installations ring magnets. To increase the intensity of the magnetic field in the area of the laser radiation it is proposed to use various types of hollow cores of soft magnetic materials, capable to have a significant impact on the character of the magnetic field distribution on the surface of the nozzle. Constructive solutions of the magnetic nozzle with combined cores were proposed to provide the formation (in the area of laser radiation ) of the magnetic field with induction, slightly different little from its value over the projection of the body of the magnet. These magnetic nozzles can also be used for magneto-phototherapy in devices based on LED sources. It-s shown, that there is the possibility of a smooth change (in the area of the radiation) of the value of magnetic induction in the range |B| = 27-75 mT due to the change of the core in regard to the plane of ring magnet. This adjustment allows to optimize the magneto-laser therapy taking into account pathology, age or physiological characteristics of individual patients.
