Abstract
A magnetic field generating device used for MRI includes a pair of magnetic pole pieces to each other to provide a gap therebetween and generate a magnetic field in the gap, the magnetic pole pieces being formed by laminating and integrating a plurality of non-oriented silicon steel sheets. By using laminated non-oriented silicon sheets the eddy current generated in the magnetic pole pieces caused by the application of GC pulses can be reduced and phenomenon of the residual magnetism can also be reduced.
