The simplest example of such a system is a single circular coil of conductive wire immersed in a magnetic field, in which case the flux linkage is simply the flux passing through the loop. The flux Φ {\displaystyle \Phi } through the surface delimited by a coil turn exists independently of the presence of the coil.
The Fibre Channel electrical interface is one of two related Fibre Channel standards that can be used to physically interconnect computer devices. The other standard is a Fibre Channel optical interface , which is not covered in this article.
Two-wire circuits in new installations are limited to intercom and military field telephone applications, though these too are being supplanted by modern digital communication modes. To communicate in both directions in the same wire pair, conversion between four-wire and two-wire was necessary, both at the telephone and at the central office.
This problem is undecidable over perfect channel systems, even when the system is a counter machine [4] or when it is a one-channel machine [3]: 26 . This problem is decidable but nonprimitive recursive over lossy channel system. [2]: 10 This problem is trivially decidable over machine capable of insertion of errors [3]: 26 .
The twelve channel scheme was first devised in the early 1930s to provide a line spectrum covering 60 to 108 kHz for the Type J Carrier Telephone System, an equivalent four wire (on two wire facilities) open wire carrier that was used almost exclusively for interstate long haul toll telephony.
f.lux (pronounced "flux") is a cross-platform computer program that adjusts a display's color temperature according to location and time of day, offering functional respite for the eyes. The program is designed to reduce eye strain during night-time use, helping to reduce disruption of sleep patterns. [2] [3]
Flux valve of a type of fluxgate compass used on airplanes. [1] The current in each of the three pickup coils changes with the heading of the aircraft. [1] To avoid inaccuracies created by the vertical component of the field, the fluxgate array must be kept as flat as possible by mounting it on gimbals or using a fluid suspension system
A very basic flux loop. A flux loop is a loop of wire. The magnetic field passes through the wire loop. As the field varies inside the loop, it generates a voltage by Faraday's law of induction, driving a current. This was measured and from the signal the magnetic flux was measured. The voltage induced is determined by: [1]
