A magnetic sensor (10), comprises at least one first coil (42) at an associated at least one first location (48) of a body of a vehicle (12) and at least one magnetic sensing element (50) operatively connected to at least one second location (52) of said body of said vehicle. The at least one first coil (42) is operatively coupled to a ferromagnetic element of a vehicle body, the at least one first (48) and at least one second (52) locations are in magnetic communication through a first portion (30) of the vehicle and through a second (32) portion of the vehicle, the first portion (30) of the vehicle comprises a portion of the body that is susceptible to deformation by a crash, the first portion (30) is distinct from the second portion (32), and at least one of the at least one first coil (42) and the at least one magnetic sensing element (50) comprises a coil of an electromagnetic device (51) selected from a motor, a solenoid, a window control motor, a seat control motor, a mirror control motor, and a door lock solenoid. At least one first signal is operatively connected to the at least one first coil, and at least one second signal is sensed from the at least one second coil, and a vehicle crash is discriminated from the at least one second signal.
