A magnetic detector for a torpedo having three rings of magnets and a pair of inducting coils alternately positioned on a torpedo body in longitudinally spaced positions thereon. Each ring of magnets and coil lies in a plane parallel to the plane of each other ring and coil and perpendicular to the longitudinal axis of the torpedo. The coils are connected in series opposition and their combined output is fed into a low frequency amplifier.
