1. A catheter for electrophysiology applications, the catheter comprising:
a tubular member extending along a longitudinal axis from a proximal portion to a distal portion; and
an end effector coupled to the distal portion, the end effector including first, second and third loop members, each loop member includes two spines and a connector that connects the two spines and the first, second and third loop members are configured so that:
the first loop member defines a first plane, the second loop member defines a second plane at an angle to the first plane, and the third loop member defines a third plane at an angle to the first plane and at an angle to the second plane,
each of the first, second, and third loop members are configured as a respective single axis magnetic coil, and
the first, second, and third loop members are collectively configured to function as a three axis magnetic sensor.
