"Magnetic shielding refers to the attempt to isolate or block the magnetic field of the MRI magnet. This can be done to prevent unwanted interference from the MRI magnet on nearby electronic devices. This is different from radiofrequency shielding, which is the attempt to prevent the unwanted interference of noise or radiofrequencies, often in order to avoid image distortion."

"An example of where magnetic shielding is important would be when there are nearby devices that potentially can be susceptible to magnetic interference, such as cardiac pacemakers, or other sensitive pieces of electronic or medical equipment. It also becomes relevant when low frequency external magnetic fields are being used nearby and need to be shielded from the magnetic field or fringe field from the MRI magnet. In general, the entire environment around the MR magnet needs to be protected from the fringe and magnetic fields."
