Winding apparatus and winding method

A winding method, performed by a winding apparatus, the winding apparatus comprising:

• a winding needle, being configured to wind a winding material on the winding needle;
• a power supply assembly, being configured to be electrically coupled to the winding needle;
• and
• a magnet supply assembly, being configured to provide a magnetic field to the winding needle, and wherein
• the method comprises:
• winding a winding material on the winding needle of the winding apparatus by rotating the winding needle;
• energizing the winding needle, by the power supply assembly, to form current on an axis of the winding needle;
• and
• providing a magnetic field, by the magnet supply assembly, to the winding needle with a magnetic field direction intersecting the axis of the winding needle so that the energized winding needle generates an ampere force for resisting deformation of the winding needle in the magnetic field when the winding material is wound on the winding needle.
