An oscillating motor and electric clippers. The oscillating motor includes a U-shaped magnetic yoke, four permanent magnets and a swing arm. The U-shaped magnetic yoke causes end faces of two support legs to produce alternating magnetic poles with the control circuit. The four permanent magnets are fixedly mounted to an inner arm via a second magnetic yoke. The four permanent magnets are sequentially distributed on a same circumferential surface having a fulcrum being a centre of rotation. The polarities of radial end faces of the first permanent magnet and the fourth permanent magnet are the same. The polarities of radial end faces of the second permanent magnet and the third permanent magnet are the same, and the opposite of the polarity of the radial end face of the first permanent magnet. When a coil is electrified, the four permanent magnets produce torque having the same direction of rotation.
