The difference between winding and coil is about how they are made and what they do. A coil is just a simple loop or a few turns of wire. A winding is more complicated and is made for special jobs. Have you ever thought about how motors or transformers work? Both winding and coil use wire, but each one has its own job in electrical devices.
