ABSTRACT An electromagnet for producing the constant magnetic field required for use in NMR tomography consists of a cylindrical field coil and a stable cylindrical shell made of iron encompassing and simultaneously supporting the coil. The field coil may comprise constituent coils, including error coils, and is capable of producing an at least approximately homogeneous magnetic field within the space defined by the field coil for receiving the object to be examined. Due to the strictly symmetric geometry of the coil assembly, the homogeneity of the magnetic field is not adversely affected by temperature fluctuations, even if the dimensions of the apparatus are such that the coil will admit a human body. The cylindrical shell, however, does not only serve as an extremely stable supporting means, but also forms the vehicle for a magnetic reflux by which the energy requirements of the magnet are considerably reduced, and further, also consitutes shielding means both against external magnetic fields and electromagnetic interference and radiation from the high frequency field produced in NMR tomography. The cylindrical iron shell may be provided at its end portions with operational members such as annular discs and tubular studs and may be closed by iron covers, so that its effectiveness may even be further enhanced.
