The current procedures and guidelines for testing forces on medical devices require that testing be performed in a MR setting, which is both timely and costly. To reduce test time and cost, a computational model of magnetic force was developed. Using a test case where an analytic solution of magnetic force can be applied, it is shown that for materials with magnetic susceptibility (chi)<105 ppm, a computational model of magnetic force was correct within 10% error and this error decreases to less than 1% for chi<104 ppm. Size of object is shown to have little effect on error.
