Abstract

A circulator suitable for use in an external field, particularly of a magnetic resonance apparatus, has a planar ferrite structure. Instead of a permanent magnet, a field conducting device is provided that is designed to strengthen or weaken an external field, and/or at least one electromagnet is provided for generating an operating field. The operating field proceeds perpendicularly through the ferrite structure.
