Abstract (en)

The present application relates to an electromagnetic heating coil, a heating assembly, and an electronic atomizing device. The electromagnetic heating coil includes a plurality of turns arranged in an axial direction. From one end to another end in the axial direction, the electromagnetic heating coil includes a first helical section and a second helical section sequentially connected to the first helical section. A pitch between any two adjacent turns of the first helical section is smaller than a pitch between any two adjacent turns of the second helical section.
