WebAnswer (1 of 3): Radiation exchange always occurs between a substance and the environment, if the two are at different temperatures. This is the only practical way to lose (or gain) heat in space. Evaporation (from a liquid surface) or sublimation (from a solid surface) can also occur in a “vacu... WebYou are examining the question really: can a magnetic field transfer energy through a vacuum, and the answer is yes. If we go back to the question asked, it is not clear that it will be in the form of heat. In the two magnets case, a vibration might be set up. If one vibrates one of the magnets (50herz for example) the vibration will be transfered.
