An elongate medical probe, having proximal and distal ends, whose position is tracked within the body of a subject includes a magnetic-field responsive optical element adjacent to the distal end, which modulates light passing therethrough responsive to an externally-applied magnetic field. The probe also includes a fiberoptic coupled to receive modulated light from the optical element and convey it to the proximal end of the probe for analysis of the modulation.
