51Superconducting magnetic energy storage — (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes… …
52Induction coil — An induction coil or spark coil (archaically known as a Ruhmkorff coil) is a type of disruptive discharge coil. It is a type of electrical transformer used to produce high voltage pulses from a low voltage DC supply. To create the flux changes… …
53Bifilar coil — A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire… …
54Electromagnetic coil — An electromagnetic coil (or simply a coil ) is formed when a conductor (usually a solid copper wire) is wound around a core or form to create an inductor or electromagnet. One loop of wire is usually referred to as a turn , and a coil consists of …
55Search coil — A search coil is a device for measuring eye movements using coils that are embedded into a tightly fitting contact lens or a rubber ring that adheres to the eye. In animal studies, the search coil may be surgically implanted into the sclera of… …
56Helmholtz coil — The term Helmholtz coils refers to a device for producing a region of nearly uniform magnetic field. It is named in honor of the German physicist Hermann von Helmholtz. Description A Helmholtz pair consists of two identical circular magneticcoils …
57Electro-magnetic induction — Induction In*duc tion, n. [L. inductio: cf. F. induction. See {Induct}.] [1913 Webster] 1. The act or process of inducting or bringing in; introduction; entrance; beginning; commencement. [1913 Webster] I know not you; nor am I well pleased to… …
58Induction coil — Induction In*duc tion, n. [L. inductio: cf. F. induction. See {Induct}.] [1913 Webster] 1. The act or process of inducting or bringing in; introduction; entrance; beginning; commencement. [1913 Webster] I know not you; nor am I well pleased to… …
59Ruhmkorff's coil — Induction In*duc tion, n. [L. inductio: cf. F. induction. See {Induct}.] [1913 Webster] 1. The act or process of inducting or bringing in; introduction; entrance; beginning; commencement. [1913 Webster] I know not you; nor am I well pleased to… …
60Near Field Magnetic Induction Communication System — A Near Field Magnetic Induction Communication System is a short range wireless physical layer that communicates by coupling a tight, low power, non propagating magnetic field between devices. The concept is for a transmitter coil in one device to …
