Depending on what plane one is in when taking the measurements, they
might *appear* quite diminished in one location, when compared to
another. Directly above or below the parallel lines, the fields would
be distinct, and separate. In the same plane that the lines traverse
at a parallel height, one might only see the field strength of the
Sort of like how directional antennas work.
But differences in the currents in them would have no effect.
Magnetic fields pass through planets. If we could "cancel" them with
opposing fields, we would probably be flying magnetic hovercraft by
