21Tesla coil — at Questacon the National Science and Technology center in Canberra, Australia Uses Application in educational demonstrations, novelty lighting, as well as music Inventor …
22Electromagnetic 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 …
23Loading coil — In electronics, a loading coil or load coil is a coil (inductor) that does not provide coupling to any other circuit, but is inserted in a circuit to increase its inductance. The need was discovered by Oliver Heaviside in studying the… …
24Magneto (electrical) — This article is about the engine component. For other uses of the term, see Magneto (disambiguation). A magneto is a device used in the ignition system of gasoline powered internal combustion engines to provide pulses of high voltage electrical… …
25Bifilar 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… …
26Low tension coil — A low tension coil is an electrical device used to create a spark across the points of an ignitor on early 1900s gasoline engines, generally flywheel engines, hit and miss engines, and other engines of that era. In modern electronic terms, a low… …
27Field coil — A field coil is a component of an electro magnetic machine, typically a rotating electrical machine such as a motor or generator. A current carrying coil is used to generate a magnetic field. Magnetic fields require a continuous circuit, thus… …
28Armature (electrical engineering) — In electrical engineering, an armature is one of the two principal electrical components of an electromechanical machine a motor or generator. The other is the field winding, field magnet. The role of the field component is simply to create a… …
29Induction 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… …
30Voice coil — A voice coil (consisting of a bobbin, collar and winding) is the coil of wire attached to the apex of the cone of a loudspeaker. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. The… …
