solenoid

IPA: sˈɔɫʌnɔɪd

(physics) A coil of wire that acts as a magnet when an electric current flows through it.
(engineering) An electromechanical device consisting of such a coil containing a metal core, the movement of which is controlled by the current.
(electronics) An electromechanical switch controlled by a solenoid; solenoid switch, relay.
(meteorology) The region of intersection between isobaric and isopycnal surfaces.

Examples of "solenoid" in Sentences

a solenoid is a spiral of insulating wire wound around a cylinder.
Now the chromatin fiber is coiled into a structure called a "solenoid".
How about designing a torque limiter that engages/disengages by some kind of solenoid mechanism?
Maxwell's Equations, the divergence of the magnetic field is zero, and "solenoid" is a traditional term for an electromagnet.
This refers to the fact that, according to [[Maxwell's equations]], the divergence of the magnetic field is zero, and "solenoid" is a traditional term for an electromagnet.
So far, injector technology has been catagorized as either "solenoid" or "piezo" In both cases, the injector needle is moved via a hydraulic circuit controlled by a valve that is set in motion by an actuator-either a 'solenoid' device or a 'piezo' device.
The solenoid is a large magnet, generating a 4 Telsa magnetic field (100,000 times stronger than the Earth’s magnetic field) with a total stored energy of 2.66 GigaJoules (equivalent to half a tonne of TNT), and is responsible for our ability to observe tracks and measure the energy of charged particles.
