Abstract
In a solenoidal electromagnet arrangement for a magnetic resonance imaging system, annular inner coils and annular end coils are provided, all concentrically aligned about an axis, the end coils being placed at axial extremities, axially outside of the inner coils. A pair of annular outer coils are provided concentrically aligned about the axis. An arrangement is provided retaining the pair of outer coils against an axial force urging the outer coils away from one another. The arrangement comprises strap elements which extend around a radially inner surface, a radially outer surface and an axially outer surface of each outer coil in certain circumferential locations. Each strap element on one of the outer coils is linked to a corresponding strap element on the other outer coil of the pair by a tensile member.
