Abstract :
Superferric technology was first applied to magnetic resonance imaging (MRI) magnets in 1986 with the design and construction of a 4-T/30-cm magnet. In an evolutionary step, this technology is being applied to the development of a whole body 4-T/1-m magnet. The design goals and design parameters of this magnet are presented. The superconductor and spices are discussed, and a passive shimming technique is described
