iPad 2 sleep sensor (red) and magnets for keeping cover closed (yellow)


Noted teardown firm iFixit reported today that it has performed a teardown of the Apple's highly-publicized Smart Cover for the iPad 2, revealing a plethora of magnets inside the device to keep it aligned on the surface of the iPad and to turn the iPad on and off.

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 in order to hold the Smart Cover firmly in place on the left side and keep the cover closed on the right side.

A single round magnet in the rightmost panel of the Smart Cover interacts with a sleep sensor embedded in the right edge of the iPad to turn the iPad on and off as the cover is opened and closed.

The Smart Cover is broken into four panels to allow it to fold into a triangular shape to serve as a stand. A total of 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.

Thought this was pretty cool how they did it.

Lots of their machine's have magnets under the housing.

Strong little magnets too. It seems like a much more efficient method than clasps, clips, etc.

Agreed. An absolutely amazing design, in my opinion, however magnets are not cheap-- especially high powered neodymium ones, such as they probably are.

That's a horrible parody; I don't know even one stupid person who believes there are hard drives in the iPad.

I remember how mesmerized I was by BlackBerrys being magically put to sleep mode by their holsters. Glad to see this tech in use for other purposes
