The guidance system of the invention includes at least two spaced, permanently magnetized regions that each produce a magnetic field. The two permanently magnetized regions can be provided at either side of another region that produces a magnetic field of less intensity than the permanently magnetized regions, and in one embodiment, the former region produces no magnetic field. The system may also include portable means for detecting the magnetic fields produced by the permanently magnetized regions, and that sensor may be mounted to a cane for use by a person. In another embodiment, the permanently magnetized regions contrast with either each other or the region that produces a magnetic field of less intensity, or have different surface characteristics, or both.
