An electrical circuit.
electrons need a closed loop called what in order to move?

A "circuit".
A closed circuit.
loop
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
It's called Ring.
the magnet is supporting weight. I say yes.
Feedback oscillators have a closed loop gain of
closed loop system
A cruise control is an example of a closed loop servo.
