Q: Answer-Whichofthefollowingprincipleisused to produce low-temperatures'?

Magnetic refrigeration is a cooling technology based on the magneto- caloiic effect. This technique can be used to attainextremelylowtemperatures,aswellasthe rangesusedincommonrefrigerators,depending on the design of the system. The magneto- caloriceffectMCE,frommagnetandcalorieis a magneto-thermodynamic phenomenon in which a change in temperature of a suitable material is caused by exposing the material to a changing magnetic field.
