Great teardown of the iPad 2 Smart Cover, and very well detailed, but missing some dimensional specs I'm really interested in. Specifically, there are six magnets in the frame / spine of the smart cover, as shown in images accompanying Step 7. There are apparently two lengths of these magnets; four of them are 'short' and two of them are 'long'. Can you please specify the dimensions of these magnets? I am particularly interested in the lengths. Thanks!
