1. A transducer apparatus for emitting an electromagnetic field for locating and/or tracking a position of a medical device, the transducer apparatus comprising:
a core;
a conductive winding with a first end, a second end, and an intermediate portion, where the conductive winding surrounds a portion of the core and is wound about a winding axis;
a protrusion for aligning the apparatus where the protrusion is parallel with the winding axis; and
a conductive connector extending from the conductive winding, wherein the conductive connector is electrically coupled with the conductive winding at the intermediate portion, the conductive winding configured to generate the electromagnetic field,
wherein the apparatus is configured to be positioned with the winding axis at an angle that is perpendicular to a longitudinal axis of the medical device to facilitate locating and/or tracking a position of the medical device.
