FERRITE

A powdered and compressed ferric oxide material that has both magnetic properties and light resistance to current flow [11].

FERRITE SWITCH

A ferrite device that blocks the flow of energy through a waveguide by rotating the electric field 90 degrees. The rotated energy is then reflected or absorbed [11].

FERROMAGNETIC MATERIAL

A highly magnetic material, such as iron, cobalt, nickel, or their alloys [1].

FERRULES

The cylindrical metallic ends of a cartridge fuse [3].

FIBER OPTICS

Conductors or optical waveguides that readily pass light [17].

FIBROUS BRAID

An outer covering used to protect a conductor's insulating material. Commonly made from cotton, linen, silk, rayon, or fiberglass [4].

FIDELITY

(1) The faithful reproduction of a signal. (2) The accuracy with which a system reproduces a signal at its output that faithfully maintains the essential characteristics of the input signal [7] [8] [12] [17].

FIELD

The electromagnet which furnishes the magnetic field that interacts with the armature in motors and generators [5].

FIELD EXCITATION

The creation of a steady magnetic field within the field windings by the
application of a dc voltage either from the generator itself or from an external source [5].

FIELD OF FORCE

A term used to describe the total force exerted by an action-at-a-distance
phenomenon such as gravity upon matter, electric charges acting upon electric charges, and magnetic forces acting upon other magnets or magnetic materials [1].
