Magnetic refrigeration is a cooling technology that utilizes the magnetocaloric effect, which is the phenomenon where certain materials, known as magnetocaloric materials, experience a change in temperature when exposed to a changing magnetic field. ### How It Works: 1. **Magnetocaloric Effect**: When a magnetocaloric material is magnetized, it typically warms up; conversely, when the magnetic field is removed, the material cools down, often resulting in a drop in temperature.
