Homework Statement
that fig is taken from the book of The Feynman Lectures on Physics. The fig above shows that if the copper disc is rotated (by a hand), there will be induced current, measured by the galvanometer. this engineering principle is the basic principle of a generator. what would happen if the situation changed? so now the bar magnet is the one that rotated (relative to the axis of the magnetic poles: NS). is there still any induced current measured by the galvanometer?
