iPad 2 Smart Cover Teardown Reveals 21 Magnets
Well-know teardown firm iFixit has recently teardown the Apple’s Smart Cover case for the new iPad 2. The highly publicized case consists of plenty magnets that keep it aligned on the surface of the iPad and turn off and on the device.
There are a total of THIRTY ONE magnets within the iPad 2 and Smart Cover: 10 magnets in the iPad 2, and a whopping 21 magnets inside the Smart Cover. They're the reason why the cover works so well with the iPad 2.
Long, thin magnets are embedded in the sides of the iPad. 15 magnets in the rightmost panel of the cover are used to bond to a steel plate in the leftmost panel to stabilize the stand. A single round magnet in the right panel of the case is to interact with a sleep sensor and to turn the iPad on and off.
