【 摘 要 】

The method of constructing of the optical image of the magnetic field intensity spatial structure distribution with the help of the ferrofluid cell is considered. The experimental research results showed, that the suggested method allows to determine in real time besides the intensity lines structure also the irregularity of the magnetic field and its direction. The possibility of the magnetic system tuning with the help of intensity field lines optical image was examined having in view the realization of necessary field parameters in the course of the experiment. The experimental research results of the magnetic system constructing and tuning quality at different temperatures are represented.
