A magnetic sensor comprises at least one first coil and at least one magnetic sensing element, operatively connected to respective first and second locations of a body of a vehicle and to a ferromagnetic element of the body. The first and second locations are distinct from one another and are in magnetic communication through a first portion of the vehicle, wherein the first portion of the vehicle comprises a portion of the body that is susceptible to deformation by a crash. A sinusoidal signal comprising a plurality of frequencies is applied to the at least one first coil, and the at least one magnetic sensing element generates a second signal responsive thereto, from which a magnetic disturbance is localized or a crash is discriminated.
