Armature
armor worn for the defense of the body, or, more frequently, the armor in which some animals are enveloped for their protection against their natural foes.
In magnetism, the armatures, called pieces of soft iron placed in contact with also the keepers, of a magnetic bar are pieces of soft iron placed in contact with its poles. These, by being acted on inin their turn, not merely preserve, but even increase, the magnetism of the original bar. Magnets thus provided are in their turn, not merely preserve, but a polarized armature, and is used in ture is made of steel and is permanently magnetized. Such an armature is termed telegraphic instruments, etc. In dynamic electricity, the armature is the shaft or central revolving arm of an ARMED NEUTRALITY electric generator, by the movement of which the current is generated.
In electricity (a) the internal and external armatures, or coatings of a Leyden jar, and the coatings of tinfoil on its interior, and part of its exterior, surface; (b) Siemens' armature or bobbin, an armature designed for magneto-electrical machines, in which the insulated wire is wound longitudinally on the core, instead of transversely, as is the ordinary arrangement.
In architecture, iron bars, employed for the consolidation of a building.
