Abstract

Forces and torques, due to a 0.3 Tesla magnetic field were evaluated on ten hip prostheses and ten hemostat clips. Measurements were performed with an instrument utilizing the movement of a laser beam caused by the deflection of a canti-lever. The results indicate effects, if any, to be smaller than the instrument's sensitivity which, at its highest, was 7 mg of force and 125 mg·cm of torque.
