2. Solenoid - Wikipedia

   en.wikipedia.org/wiki/Solenoid

   A solenoid (/ ˈ s oʊ l ə n ɔɪ d / [1]) is a type of electromagnet formed by a helical coil of wire whose length is substantially greater than its diameter, [2] which generates a controlled magnetic field. The coil can produce a uniform magnetic field in a volume of space when an electric current is passed through it.

3. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   A small solenoid can generate a limited force. An approximate relationship between the required solenoid force F s, the fluid pressure P, and the orifice area A for a direct acting solenoid valve is: [3] = = where d is the orifice diameter. A typical solenoid force might be 15 N (3.4 lb f).

4. Solenoid (engineering) - Wikipedia

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

   [2] [3] [4] In electromagnetic technology, a solenoid is an actuator assembly with a sliding ferromagnetic plunger inside the coil. Without power, the plunger extends for part of its length outside the coil; applying power pulls the plunger into the coil. Electromagnets with fixed cores are not considered solenoids.

5. Inductance - Wikipedia

   en.wikipedia.org/wiki/Inductance

   A solenoid is a long, thin coil; i.e., a coil whose length is much greater than its diameter. Under these conditions, and without any magnetic material used, the magnetic flux density B {\displaystyle B} within the coil is practically constant and is given by B = μ 0 N i ℓ {\displaystyle B={\frac {\mu _{0}\,N\,i}{\ell }}}

6. Nail gun - Wikipedia

   en.wikipedia.org/wiki/Nail_gun

   Here a solenoid propels a metal piston, which has a long front rod which propels the nail. The solenoid tends to attract the piston or projectile towards the middle of the solenoid. If a series of solenoids is used (which makes the nail gun into a type of coilgun ), to get more power, each solenoid must be switched off when the piston has ...

7. Compact Muon Solenoid - Wikipedia

   It is 13 m long and 6 m in diameter, and its refrigerated superconducting niobium-titanium coils were originally intended to produce a 4 T magnetic field. The operating field was scaled down to 3.8 T instead of the full design strength in order to maximize longevity. [13]
