A method for manufacturing an electromagnet assembly, according to one embodiment, can comprise the steps of: preparing a frame including a protruding part and an edge part surrounding the protruding part; disposing a coil on an outer circumferential surface of the protruding part so as to encompass the protruding part; heating a thermal conductive material having a solid state at a room temperature and a normal pressure so as to change the same to a liquid state; filling a space between the protruding part and the edge part with the thermal conductive material in a liquid state; and disposing, after the filling step, a permanent magnet at the center of the coil.
