The interaction between the gradient induced eddy current and the static magnetic field in the MRI system generates force and torque to a conductive implant if the eddy current magnetic moment and static magnetic field are misaligned. A frequency-domain solver (F-solver) of full-wave simulator CST studio suite 2015 was employed as an initial step to calculate the surface current induced due to the gradient field-induced switching.
