electromagnetic geophone
The simplest, most widely used type of geophone. It consists of a coil and a magnet, one rigidly fixed with respect to the Earth and the other suspended from a fixed support by a spring. Any relative motion between the coil and magnet produces an electromotive force across the coil's terminals that is proportional to the velocity of the motion.
