Control of strain development in an MgB2 based full body MRI magnet is a challenge towards realizing a conduction cooled system. It is possible to alter the strain development in an MRI magnet by modifying the coil winding support conditions and by varying the winding stress on the wire across the layers. A multiscale multiphysics model is employed to study the strain comparison by varying support conditions and winding prestress. Results conclude, radial support with constant winding prestress generates about 50% less stress and 42% less strain compared to no mandrel support.
