There are noises coming out of a speaker that nobody can hear. Holding a microphone in front of the speaker amplifies these noises. They come back out the speaker. Holding a microphone in front of the speaker amplifies these noises. They come back out the speaker. This creates an infinite loop of sound going from the speaker to the microphone and back to the speaker, which is what causes the high pitched squeal known as 'feedback'.

They do. It's called feedback, and it's caused by the sound hitting the membrane in the mic at the same time it's coming out of the speaker. You can consider it a sort of "system overload."

Feedback. It's also why if a radio station is talking to a caller, they tell them to turn down their radio.
It's caused by a continous loop. Ergo "feedback", could as easily be called "loopback".
