1. A medical system comprising:
a probe adapted for insertion into an organ of a living subject, the probe having a distal end;
a framework disposed on the distal end, the framework comprising a plurality of wire loops that are each electrically conductive and connectable to a receiver, each wire loop of the plurality of wire loops comprising a single conductive loop configured to function independently as a single-axis magnetic location sensor when subjected to a magnetic field generated by a magnetic position tracking system and output signals in response to the magnetic field;
an electrode attached to each wire loop of the plurality of wire loops; and
a processor configured to:
receive signals from the plurality of wire loops indicative of a magnetic flux induced by the magnetic field on each wire loop of the plurality of wire loops; and
determine, based at least in part on the signals, a location and orientation of the framework; and
output a position and orientation of the probe in the organ.
