Abstract
A coil assembly comprises four coils for generating a static magnetic field in an NMR imaging apparatus, wherein the dimensions of the coils are selected so that the flatness of the cross section of the coils, the current turns ratio, and the radius ratio, are within certain limits. The assembly so constructed produces highly uniform magnetic field, is small in size, and light-weight, and consumes a lower amount of power, and can be manufactured inexpensively.
