Ever increasing liquid helium (LHe) price has pushed researchers to design background magnets that could operate in conduction cooling mode. High Tc superconductor e.g. MgB 2 is a promising candidate for conduction cooled magnet. But high strain sensitivity of MgB 2 wire could be a limiting factor in designing a whole body MRI magnet of 1.5T or higher. In this work, strain sensitivity of an optimized 1.5T conduction cooled MgB 2 MRI magnet is numerically studied. The stress and strains behavior of the design shows viability of building such conduction cooled magnet.
