ABSTRACT:
At least one electrically conducting wire is coated with an electrically insulating material and wound in non-tightly coiled turns in a uniform direction of rotation. A direct electrical current is passed in the turns of the winding, preferably by repetitive sequences interspersed with stop periods, so as to create therein electromagnetic forces of mutual attraction between the turns, tending to bring them closer together in pairs and thus to reduce the height of the winding.
