Examples of solenoids in a Sentence
A magnet which consists entirely of such solenoids, having their ends either upon the surface or closed upon themselves, is called a solenoidal magnet, and the magnetism is said to be distributed solenoidally; there is no free magnetism in its interior.
If the constituent solenoids are parallel and of equal strength, the magnet is also uniformly magnetized.
Ampere had already previously shown that a spiral conductor or solenoid when traversed by an electric current possesses magnetic polarity, and that two such solenoids act upon one another when traversed by electric currents as if they were magnets.
Most existing electronic locks use power-hungry solenoids to actuate the release mechanism.
They all control the air solenoids differently to the road boxes so need big jetting changes to run.
Some commands to move to another port then switched gas solenoids on and off in seemingly uncontrolled fashion.
The air supply will be controlled by air solenoids which in turn are controlled by automotive indicator relays to provide the pulses.
The 1992 and 1993 Cadillac DeVille had vacuum lines and solenoids that often become brittle and crack, requiring replacement.
