An electric guitar does not feedback through magnet loops, I have done this with home made E-bow like things (electromagnetic bows) and the sound is much different. What you hear is the speaker moving enough air to move the body of the guitar, this then moves the strings. If the the strings are stopped then you will hear squealing which is usually through the pickups which, when older and not waxed, will act as poor microphones at the same time as electromagnetic pickups. A string will move sympathetically but usually it is the body it is attached to which is designed to radiate sound, and therefore sensitive to sound itself, which moves most.
