Armature n.

Armor; whatever is worn or used for the protection and defense of the body, esp. the protective outfit of some animals and plants.

(Magnetism) A piece of soft iron used to connect the two poles of a magnet, or electro-magnet, in order to complete the circuit, or to receive and apply the magnetic force. In the ordinary horseshoe magnet, it serves to prevent the dissipation of the magnetic force.

(Arch.) Iron bars or framing employed for the consolidation of a building, as in sustaining slender columns, holding up canopies, etc.

(Elec.) That moving part of a dynamo or electric generator in which a current is induced by a moving through a magnetic field, or, in an electric motor, the part through which the applied current moves, thereby generating torque. The armature usually consists of a series of coils or groups of insulated conductors surrounding a core of iron.

... and possessing a magnetic field as extensive as space itself. The magnetic field is the stress or pressure in the ether produced by the magnetic body. This ether pressure produced by a magnet may be as great as a ton per square inch. It is this pressure that holds an armature to the magnet. As heat is a molecular condition of vibration, and radiant energy the result of it, so is magnetism a property of molecules, and the magnetic field the temporary condition in the ether, which depends upon the presence ...
