armature

In a motor or generator, the wire-wound coil that carries the current and rotates in a magnetic field. (In alternating-current machines, the armature is sometimes stationary.) The pole piece of a permanent magnet or electromagnet and the moving, iron part of a solenoid, especially if the latter acts as a switch, may also be referred to as armatures.

armature

In modelling and sculpture, the skeleton-like metal framework used to give internal support to the clay, wax, or other material, and prevent it from sagging or collapsing. Armature wire is produced in varying thickness, but simple structures can be made from chicken wire and padded with wood or paper.
