摘要：

A unitary superconducting electromagnetic structure (10) and method of forming same for use particularly at magnetic intensities greater than the magnetic saturation of iron and including an inner body (12) containing a coil pack (40) and an outer magnetic iron body (16) about the inner body (12) in concentric relation thereto. The outer body (16) has an end assembly (18) adjacent each end of the inner body (16) and the outer iron body (16) increases the magnetic field intensity at intensities substantially above the saturation of the magnetic iron in the outer body (16). The design of the electromagnetic structure (10) is based on a computer program which utilizes accurate information concerning the mechanical, thermal, electrical and magnetic properties of the materials proposed for the electromagnet including particularly the thermal and magnetic properties of the iron for predicting precisely the magnetic permeability of the iron at all values of the magnetic field.
