WebNo, a static magnetic field does not conduct heat. The only way for thermal energy to cross a vacuum is by radiation. Of course, radiative heat transfer actually does consist of electric and magnetic fields: hot objects give off electromagnetic waves, which travel through the vacuum and are absorbed by, say, the walls of the vacuum chamber. WebIn a vacuum, heat gets transferred by the radiation mode of heat transfer. The radiation mode of heat transfer does not need any medium to propagate. Heat gets transferred in the form of electromagnetic waves. For example in space sunlight is transferred by radiation. Suggest Corrections. hot rod girls 1956Webcaused by thermal energy being radiated from particles due to their energy. heat is the ramdomized (i.e. neglecting bulk flows) energy of motion in any material (including, for instance, photon gases). Any vacuum that we can make or have access too includes a small amount of matter, and the temperature of that stuff can be measured. hot rod gear box
