From iFixit iPad 2 Smart Cover Teardown
We never took apart a case before, but the Smart Cover piqued our interest as soon as Steve Jobs announced it alongside the iPad 2. We knew it worked with magnets, but exactly how? What did it attach to? How can something so simple be so multi-functional? A Smart Cover went under the knife (literally) to provide the answers to these questions.The magnets are used to clip the Smart Cover to the iPad, keep it attached when closed, maintain trangular shape when folded, and instantly wake the iPad when opened (and sleep when closed).
