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. Web23 mei 2012 · Magnetic refrigeration is an emerging technology in the field of refrigeration. Magnetic material expels the heat when it is magnetized and absorbs the heat when it is demagnetized.
