Web11 aug. 2024 · This means that the magnetic field strength begins to decrease more slowly as you move further away from the magnet. In effect, this results in an elongated “tail” to the fringe magnetic field. As a consequence, the fringe field can often extend beyond the limit of the MRI scanning room, and needs to be accounted for and often shielded.
