A method of sensing vibrations or displacements remotely is provided. Magnets are attached to vibrating objects or the vibrating objects themselves are magnetic. A number of magnetic sensors are placed a specified distance from the magnets. Vibrational displacement of the vibrating objects is determined according to a model that maps changes in magnetic field to vibrations or spatial displacements.
