Computer controlled system for producing uniform magnetic fields and its application in biomedical research

Methods of modeling and optimization are described for coil systems that produce magnetic fields of prescribed uniformity within a maximal volume, while minimizing stray fields. Two examples of application to biomedical research are analyzed in detail. One of them deals with animal exposure systems at 60 Hz within a confined space. The other considers exposure of cell cultures simultaneously to various strengths of magnetic fields (within a range of 1:10 000) in a single laboratory incubator. Design formulas and curves are provided; power supply systems for the coils and their computer control are also outlined.
