Abstract
One presents the mBH device for measuring static B-H relationships of ferromagnetic materials, whose functioning model had been developed with the help of ICPE SA. Initially, the measuring principle was presented in the PhD Thesis of eng. P. Andrei [1], but the first physical version of the device had some deficiencies and could not reach magnetic flux densities values higher than 1.8T. Thus, new geometries of the magnetic circuit were proposed, using field concentrators, together with the development of computation programs for the magnetic flux-magnetic voltage relationships of the magnetic circuit branches. The tests on the device confirmed the correctness of the proposed method.
Keywords: measuring the static B-H relationship, magnetic circuit branches
