1. A magnetizer system configured to impart one or more magnetic signatures to a medical device having ferrous elements for medical-device tracking, comprising:
a magnetizer having an elongate body defining a longitudinal axis and comprising:
a single-dipole section having a cavity defining a central axis extending parallel to the longitudinal axis and configured to receive a first medical device along the central axis;
a multipole section having a trough extending parallel to the central axis of the single-dipole section and configured to receive a second medical device perpendicular to the longitudinal axis; and
a first magnetic element disposed within the elongate body of the magnetizer and between the central axis of the single-dipole section and the trough of the multipole section, the first magnetic element imparting a first magnetic signature on the first medical device or a second magnetic signature on the second medical device.
