The electromagnetic heating device comprises a hollow metal pipe and a wire wound on the outer wall of the metal pipe, and the wire is connected with a battery power supply 3. The metal casing 1 is provided with a passage for passing low-temperature atomized tobacco tar. The aerosol droplets atomized by the low-temperature atomizer 6 flow through the heated metal tube and are heated, and then are sucked by the smoker through the mouthpiece 2.
