How to pronounce“solenoid”in English

solenoid valve and from there it's just 22 mil pipe straight up to the end of the barrel and the idea is to get a fast flow of gas up to where it's burning so

the solenoid. I'll be invoking this result all the time.

The longer the solenoid, the weaker the field in the surrounding space.

When the solenoid is off, there is no magnetic field in the region the electrons are traveling through, and there is no magnetic potential.

But when the solenoid is turned on, well, there is still no magnetic field because it's confined entirely within the coil, but there is a magnetic potential.

But below the solenoid, it points in the same direction as the beam.

An ideal solenoid would have to be infinitely long, which is physically impossible.
