Abstract

A circulator has a ferrite, and the circulator is arranged in the vicinity of a device that produces a static magnetic field in the environment surrounding the device, this static magnetic field giving the circulator a non-reciprocal behavior, with respect to circulation of energy among the gates of the circulator, as a result of interaction of the ferrite with the static magnetic field. A magnetic resonance apparatus embodies such a circulator, and the basic field magnet of this magnetic resonance apparatus generates the static magnetic field.
