I've been meaning to post this for a bit:
Helmholtz coil - supposedly it has some weird "magnetic" anomalies.
The following are all from the wikipedia page: https://en.wikipedia.org/wiki/Helmholtz_coil
Helmholtz coil schematic drawing:
There is some interesting info over at: THE STUBBLEFIELD PAPERS

Helmholtz coil schematic drawing:
Magnetic field lines in a plane bisecting the current loops. Note the field is approximately uniform in between the coil pair. (In this picture the coils are placed one beside the other: the axis is horizontal)
Contours showing the magnitude of the magnetic field near the coil pair. Inside the central 'octopus' the field is within 1% of its central value B0. The five contours are for field magnitudes of , , , , and .
