2. Solenoid - Wikipedia

   en.wikipedia.org/wiki/Solenoid

   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 ...

3. Solenoid (engineering) - Wikipedia

   en.wikipedia.org/wiki/Solenoid_(engineering)

   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).

4. Flyback diode - Wikipedia

   en.wikipedia.org/wiki/Flyback_diode

   Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.

5. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   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.

6. Henry (unit) - Wikipedia

   en.wikipedia.org/wiki/Henry_(unit)

   The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...

9. Electromagnetic induction - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_induction

   A solenoid The longitudinal cross section of a solenoid with a constant electrical current running through it. The magnetic field lines are indicated, with their direction shown by arrows. The magnetic flux corresponds to the 'density of field lines'. The magnetic flux is thus densest in the middle of the solenoid, and weakest outside of it.
