Just marvel at the engineering behind the iPad 2’s Smart Covers. Between them, the iPad 2 and its Smart Cover contain an incredible 31 magnets.
Apple has made extensive use of magnets in the past – to hold a remote control to the iMac, for example, or keep the lid of a MacBook closed. But it has never used so many magnets in a product, or so elegantly.
The 31 magnets in the iPad 2 and the Smart Cover:
- clip the Smart Cover to the side of the iPad
- Keep the Smart Cover attached to the screen when closed
- ensure the Smart Cover retains its triangular shape when folded into a stand
- instantly wake the iPad and put it to sleep when opened and closed
It’s really quite mind-boggling. iFixit has the details.
