iFixit found that the magnetic magic of the highly functional Smart Cover is all made possible thanks to the 21 two-pole magnets found within. These internal magnets snap to the ten magnets found within the iPad 2 itself, making a total of 31 magnets all clicking together in harmony.
They also discovered that just one of the Smart Cover's many magnets is used to wake/sleep the device, but according to iFixit, other magnetized tools can also do the on/off job (pictured below).
The folks at iFixit are known for offering solid advice on repairing your various tech goods, but be warned: A sliced Smart Cover has a humorous repairability score of zero.
More information on the 'teardown', including more pictures, can be found on the iFixit site.
