Bifilar coil. A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical 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 for transformers. Wire can be purchased in bifilar form, usually as ...
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
History of the Tesla coil. Henry Rowland's 1889 spark-excited resonant transformer, [1] a predecessor to the Tesla coil. [2] Steps in Tesla's development of the Tesla transformer around 1892. [3] (1) Closed-core transformers used at low frequencies, (2-7) rearranging windings for lower losses, (8) removed iron core, (9) partial core, (10-11 ...

Resonant inductive coupling or magnetic phase synchronous coupling[4][5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
Electromagnetic coil. The magnetic field lines (green) of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). [1][2] Electromagnetic coils are used in electrical engineering, in applications ...
Coil winding technology. In electrical engineering, coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill ...
Tesla moved there to study the conductive nature of low pressure air, [3] [4] [5] part of his research into wireless transmission of electrical power. The lab possessed the largest Tesla coil ever built, 49.25 feet (15.01 m) in diameter, [6] which was a preliminary version of the magnifying transmitter planned for installation in the ...
