Magnetic Refrigerant Compositions and Processes for Making and Using

A magnetic process comprising: subjecting a magnetically susceptible media to a magnetic field wherein the fluid is magnetized and the magnetized media absorbs the heat of magnetization; transferring the absorbed heat from the magnetized fluid or solid to a heat sink; removing the magnetized magnetic media from the magnetic field wherein the magnetic media undergoes spontaneous cooling to produce a cooled magnetic media; and providing heat to the cooled magnetic media from a heat source and wherein said process is accomplished at above about 275 degrees Kelvin
