Magnetic resonance imaging (MRI) scans are often prohibited for patients with an implanted device, such as a pacemaker. There are multiple reasons for this prohibition. One reason is the physical torque on the device due to the MRI's magnetic field. Suppose a patient’s pacemaker implant requires ?=1.6 mA of current to function. The leads of the device travel close together...
