Magnetic refrigeration utilizes the thermodynamic process known as the magnetocaloric effect. Metals that exhibit the magnetocaloric effect change temperature when they are subjected to a magnetic field. Place the material in the magnetic field, and it will heat up. Remove the magnetic field, and it returns to room temperature cycle for magnetic refrigeration in position 1: A fan blows air past this cold fluid into the freezer to keep the freezer temperature at approximately 0°F.
