A computation code based on FEM was applied for calculation of current flow on gradient coil conductors. In the high frequency gradient fields (over 500Hz), eddy current appeared remarkably on wide conductors. We find narrow conductors can effectively reduce the eddy currents, and we confirmed the effect of heating suppression by the experiments.
