FERRITEA powdered and compressed ferric oxide material that has both magnetic properties and light resistance to current flow [11]. |
FERRITE SWITCHA 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 MATERIALA highly magnetic material, such as iron, cobalt, nickel, or their alloys [1]. |
FERRULESThe cylindrical metallic ends of a cartridge fuse [3]. |
FIBER OPTICSConductors or optical waveguides that readily pass light [17]. |
FIBROUS BRAIDAn 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]. |
FIELDThe electromagnet which furnishes the magnetic field that interacts with the armature in motors and generators [5]. |
FIELD EXCITATIONThe 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 FORCEA 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]. |
