Abstract

Disclosed are a winding apparatus and a winding method, the winding apparatus includes: a winding needle, being configured to wind a winding material; a power supply assembly, being configured to be electrically coupled to the winding needle, so as to form current on an axis of the winding needle; and a magnet supply assembly, being configured to provide a magnetic field to the winding needle, a magnetic field direction intersecting the axis of the winding needle so that the winding needle generates an ampere force for resisting a deformation of the winding needle in the magnetic field when the winding material is wound. By the above method, the present application may reduce the deformation of the winding needle, reduce a defective rate of a winding product formed by the winding of the winding material, and improve quality of the winding product.
