A finite solenoid is a solenoid with finite length. Continuous means that the solenoid is not formed by discrete coils but by a sheet of conductive material. We assume the current is uniformly distributed on the surface of the solenoid, with a surface current density K ; in cylindrical coordinates : K → = I l ϕ ^ . {\displaystyle {\vec {K ...
A solenoid valve is an electromechanically operated valve. Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid , and the type and characteristics of fluid they control.
The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a dual solenoid system would be self cycling. The proportional concept is more fully described in SAE publication 860759 (1986).
Drawing of a Solenoid with magnetic field lines. Note that the shape of the field lines is just roughly sketched using ellipses. In reality, the shape is vastly different and the lines ought to be most curved close to the solenoid surface. More faithful versions are available below.

English: Diagram of a solenoid and its magnetic field lines. The shape of all lines was computed according to the laws of electrodynamics. The shape of all lines was computed according to the laws of electrodynamics.
The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it. When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to ...
SYDNEY (Reuters) -The remaining five members of the "Bali Nine" Australian drug ring have returned from Indonesia after diplomatic efforts between the countries this month to strike a repatriation ...
The key to understanding the latch is in recognizing that the "Start" switch is a momentary switch (once the user releases the button, the switch is open again). As soon as the "Run" solenoid engages, it closes the "Run" NO contact, which latches the solenoid on. The "Start" switch opening up then has no effect.
