A magnetic sensor comprises at least one first coil at an associated at least one first location of a body of a vehicle and operatively connected to a ferromagnetic element of the body. A signal comprising a leading edge is applied to the at least one first coil, and a second signal is sensed from the at least one first coil, wherein said second signal is responsive to the interaction of the first signal and the ferromagnetic element, and a magnetic disturbance is localized or a crash is discriminated responsive to the second signal.
