After a layer of insulation is applied the next winding is wound in the opposite direction with the turns crossing every 180 degrees over the turns in the lower layer. The net effect of this is that the magnetic forces that are responsible for creating ‘reactance' are equal and opposite - thereby cancelling each other.
