ABSTRACT:
This process produces a small toroidal winding used, for example, to make very stable, thin magnetic magnatometers. To produce a winding having turns which are perfectly radial with respect to a cylinder, use is made of an internal cylinder and an external cylinder provided with slots arranged along the generatrixes of these cylinders. Hairpin-shaped conductive wires are introduced into these slots and welded to one another.
