This invention discloses a highly sensitive, low-noise, and fast-response magnetic fuze applied to high-speed platforms. The magnetic fuze utilizes a differential method with two coils fixed in place to detect the residual magnetic field of a target. The two coils are differentially mounted on the high-speed platform, parallel to the platform's longitudinal axis, with the two coils 0.1m apart. This invention employs a dual-coil method, with the differential detection of the induced electromotive force generated by the ship's residual magnetism serving as the magnetic fuze's magnetic field detection mechanism.
