magnetocaloric effect

The magnetocaloric effect is a phenomenon where certain materials change temperature when exposed to a magnetic field. When magnetized, magnetic moments within the material align, releasing heat and warming the material. Conversely, removing the magnetic field causes these moments to become disordered, absorbing heat and cooling the material. This effect can be harnessed for efficient cooling systems, offering an environmentally friendly alternative to traditional refrigeration by cycling magnetic fields to control temperature without harmful chemicals.
