As part of a collaborative effort to create a novel compact high-temperature superconductor 1.5 T head-only scanner for improved accessibility of MRI and advanced motor coordination studies, we are developing a 31-coil Multi-Coil (MC) array for linear and non-linear image encoding and concomitant B0 shimming. Here we present a preliminary characterization of the expected eddy currents generated by the unshielded MC array in the unusual scanner assembly at hand based on finite element based electromagnetic simulations.
