The invention relates to a motion magnetic shielding and synonym magnetic pole surface type power generation method and an induction generator, belongs to the field of mechanical energy power generation, and relates to the field of electric power energy. The problem that in the electric energy output process of an existing mechanical active induced generator, relatively huge magnetic resistance exists in a generator rotor is avoided. According to the invention, by mainly adopting a mechanical energy induced power generation method, a magnetic shielding body carries out shielding magnetic fieldmotion between a stator magnet and a stator coil which are relatively fixed and static, so the magnetic field passing through the coil is changed; an induced electromotive force is generated in the coil; magnet synonym magnetic pole surfaces are alternatively laid and fixed on the surface of the magnetic shielding body in a direction perpendicular to the moving direction; a magnetic attraction force and a magnetic repulsion force exist between the magnetic field of the magnet synonym magnetic pole surface, and the magnetic field of the stator magnet and the magnetic field of the induced current in the coil at the same time; and a relative offset balance effect of the magnetic field forces exists between the magnetic attraction force and the magnetic repulsion force, thereby reducing the magnetic resistance in the moving processes of the magnetic shielding body and achieving the purposes of saving energy and generating electricity.
