The invention discloses a mixed electromagnetic field stirring device and a working method. A hybrid electromagnetic stirring device comprises a crystallizer, a plurality of salient poles I are arranged on the outer circumference of the crystallizer at intervals, the crystallizer is sleeved with an iron core, a plurality of salient poles II are arranged on the inner circumference of the iron core at intervals, and each salient pole II is provided with a permanent magnet and a coil assembly; the iron core is formed by laminating a magnetic conductive material; the magnetizing directions of the adjacent permanent magnets are opposite; the number of the salient poles II is greater than that of the salient poles I; the winding direction of the coil group on the salient pole II is parallel to the flowing direction of non-ferrous metal in the crystallizer; and an air gap is reserved between the salient pole I and the salient pole II. A rotating magnetic field is generated in the non-ferrous metal liquid in the crys
