cool magnet: a little bit of iron gives magnetic refrigeration a boost
Big magnet. Time materials, find roles in products from cars to medical careImaging System. Now, a team of engineers has improved a custom Manufactured magnetic materials increase the likelihood that refrigeration will soon join the magnet roster Based on technology. To improve the efficiency of refrigerators and air conditioners, several groups around the world are developing magnetic- Refrigerant material. A magnetic- Since the cooling system does not use chemicals that are harmful to the environment, such as ammonia or fluorine chloride, it may also be less polluted than the current system. More importantly, the technology requires only a very small amount of moving parts, so it can be simple, silent and reliable. When a magnetic The refrigerant material is exposed to the magnetic field, which forces the spin alignment of the electrons in the material. As a result, the material is heated. Removing the field can relax the electrons to a less state. Order status, material cooling.
