Abstract
A length of wire is toroidally wound, and then the toroid is encapsulated and cut in two along a plane that is perpendicular to the toroidal axis. The resulting portions are used as stator and/or armature of a solenoid, and in the solenoid the cut face of each forms one side of the solenoid's working gap so that the faces move toward and away from each other as the solenoid operates.
