Device for generating a magnetic field in an air gap

摘要

A device for generating a magnetic field in an air gap, particularly for a magnetic resonance apparatus, has a pair of magnetic poles arranged opposite one another with the air gap therebetween. Each magnetic poles plate constructed of a number of layers successively lying on top of one another and electrically insulated from one another. Each layers is formed by plate-shaped elements of magnetically permeable material arranged next to one another and electrically insulated from one another. Successive layers are arranged offset relative to one another in in-layer directions.
