By definition, a coil is an electrical passive device, which have two terminals, use in electrical circuits to keep the power in magnetic field or to detect the magnetic fields. In winding process, is possible to appear different defects, or issues which can cause in time problems in functionality of products. In this paper, we will analyze two types of defectives what were observed in winding process. In first type of defect, some wires of beginning of winding remain out of normal winding, and the wires are visible from outside, and in second type of defect, same beginning of winding remain inside of coil, under the normal winding, not in correct position. For simulation, we will used an assembly compose by anchor, electromagnet and coil. Those are parts of contactor.
