Explain how the insulated copper conductor should be wound around the cylindrical frame of the coil

Explain how the insulated copper conductor should be wound around the cylindrical frame of the coil so that no magnetic field is generated when an electric current passes through it.

It is necessary to fold the wire in half, fix the bend line on the coil and wind the required number of turns. In one half of the conductor, current will flow in one direction, in the other in the opposite direction. The field created by the current in one direction will be directed against the field created by the current in the other direction. The resulting field will be zero. This winding is known as bifilar winding. It is used in the manufacture of wire resistances.
