1. A localization tool for localizing a nodule of a patient, comprising:
a housing;
an elongated body portion having a proximal end disposed proximal to the housing and a distal end terminating within the housing;
a magnetic core disposed within the housing and coupled to the distal end of the elongated body portion, the magnetic core configured to attract a magnetic fiducial associated with a position of the nodule;
an electrocautery element coupled to the elongated body portion and disposed within the housing, the electrocautery element configured to be coupled to a source of energy for delivering energy to tissue to mark the tissue;
a metal coil wrapped around the electrocautery element and the magnetic core, the metal coil configured to generate a magnetic field; and
a magnetic field sensor attached to the housing and configured to sense a magnetic attraction of the magnetic fiducial to the magnetic core, wherein the magnetic field sensor is in communication with a processor configured to determine a distance between the magnetic field sensor and the magnetic fiducial marker based on the sensed magnetic attraction for display of the determined distance on a display device.
