How can you determine where magnetic energy lines intersect on Earth?
A lot of information on this question seems unscientific, and I wish to find reliable information about where these intersections occur and how to find them.

They don't intersect. They are all parallel, and when you get to the node that is a pole, they come together closer but just bundle up and sink into the earth.
Magnetic energy "lines" is more a concept used for thinking about how they work than a reality, in that the magnetic forces are distributed across a plane.
When you see what appears to be lines (see the image in  below) by using iron filings to show a magnetic field, that is an artifact of using chunks of matter for the demonstration, and not an actual view of the field "lines".
There are maps available (such as  below) of the direction of the magnetic fields as measured.
There is an excellent explanation of the way it works with a map showing how declination has changed over the years at  below.Source(s):  http://www.phys.psu.edu/people/display/?person_id=...  http://user.netonecom.net/~swordman/graphics/craft...  http://geomag.usgs.gov/intro.php

Magnetic field lines to not actually intersect at all: they always run roughly parallel to each other.
While they get closest to each other at the North and South Magnetic Poles, there is no actual intersection, even if you were able to go deep beneath the Earth's surface.

If you are thinking about Sedona or something, forget it. Geophysists have gone to places like that and there is ZERO magnetic anomaly.

You should review the concept of field lines!
