    * Magnetic Cooling

    MAGNETIC COOLING IT IS OBTAINED BY THE magnetisation followed by DEMAGNETISATION OF A PARAMAGNETIC SALT. It is based on the fact that there are some materials which raise their temperatures when adiabatically magnetised, and decrease their temperatures when adiabatically demagnetised. Each atom of the paramagnetic salt may be considered to be a tiny magnet. Initially […]
