In the same vein, I've often wondered if magnetically shielding the
bottom of the robot (much like shielded speakers) would help with the
rebar problem.

An idea occurs to me. Thinking the main magnetic influences were
below you in rebar and what not. Imagine a compass on a variable
hieght mast. Take readings down, middle and up. Do you suppose
you could calculate the ultimate limit of the field with non
interference from "plotting" the progressive changes with the
compass higher and higher in the magnetic field?
