The horizontal axis represents the z-axis. The vertical axis represents the x-axis. The third axis represents the y-axis. The positive y-axis labeled, south. The negative y-axis labeled, north. The positive z-axis labeled, east. The first dipole is placed in the y z plane along the x axis. The second dipole is placed in the y z plane along the z axis opposite to the first dipole. A line in between the y z plane makes an angle theta with the z-axis.
