Carmen Lucas, a scientist at DRDC Atlantic in Dartmouth, NS, created this visualization with IDL:

Carmen explains that this is:

... the magnetic scalar potential surface and contour, and associated magnetic flux density vector field B. Note the flux density field getting "pumped" uphill inside the two magnets as shown on the surface plot.

It's been awhile since I've shown a cool visualization made with IDL, so thank you, Carmen, for sharing this!
