Advantages claimed for amorphous magnetic material are that it has asmall coercive force, comparatively large permeability, specific resistance anda manufactual characteristic which distinguishes it from other materials bythe fact that its tape thickness can be made thin.A bridge—connected magnetic circuit described here, which is a new devicebased on the best use of these excellent characteristics, consists of a toroidalamorphous magnetic core with high permeability and small coercive force andof other magnetic core with low permeability. The magnetic core with lowpermeability is 'made in a U—l'orm and is bridge connected with a toroidalamorphous magnetic core in its center.The new advantage of the flux control of this circuit is that it cancontrol the maximum flux value easily, maintaining still the symmetry ofmagnetic hysteresis loop of the core,By making use of this characteristic it is possible to make a new formof instrument and control devices with good characteristics. But, the analysisof this magnetic circuit, in detail, has been left unsolved.This paper describe an analysis of behaviour of this magnetic circuit.
