Tons of probe-construction photos
Shim coils: shapes and effects
Poole Thesis: See pp 39–58 of pdf file for lots of graphics.

Manufacture of MRI shim coils: See pp 89–93 of pdf file for graphics.
Note that the current in the two halves of each coil flows in opposite directions,
in order to establish a gradient in the appropriate direction (x, y, or z).
