Introduction: MAGNETIC ATTRACTION ... of an ... IPad 3

This Instructable shows the magnetic design of the iPad 3...
And the very unique Magnetic Cover ( Red Leather of my selection )

Objective here is to understand how the iPad uses magnets to operate this highly innovative product..

You will see the impressive array of magnet placement in the glass and aluminum iPad
and equally impressive leather cover, fairly bristling with what I assume, are NIB1 magnets.


1.]   NIB = Neodymium Iron Boron super  magnets

Step 1: FINDING the LATCH MAGNETS

My red leather cover  magically protects my  iPad
and among other features magnetically latches on, whenever the screen is closed.

Notice the North Poles in the cover are opposite the South Poles embedded in the iPad
and vice verse.

The opposing magnetic poles are strongly attracted to each other and hold the cover closed.
Remember "Like poles Repel Each Other"..

Also note, of the fourteen [14] magnets in the first leaf of this cover, not counting the little round one,
only four [4] of the five [5] in first column magnets actually Latch up with the four [4] in the embedded screen.

Step 2: What Is That Little Circular North Pole in the Cover ??

Magnetic Attraction

That little North Pole tells the iPad to shut down when present.

The South Pole does not work !!

·The video shows how a tiny North pole magnet can turn the iPad3 off..

Step 3: SPEAKERS HAVE MAGNETS TOO

See the speaker sound grill made of an array of 308 equally dispersed holes..

A compass indicates there is a North Pole on the back of the iPad 3...
And a pair of South Poles on the front screen side..

And a magnetic flux viewer shows a pair of speakers residing inside .

The film is dark green where flux lines are passing through the film ( out of this page ).
And the film is light where the flux lines travel inside ( parallel ) with the film.
Also the last magnetic picture graphic stays with the film until a new flux alters the image.

Step 4: HINGE MAGNETIC ATTRACTION

The Hinge mount attachment is the most interesting.
Made of two sets of three magnets each, one long  and two short.

These magnets center the cover and only allow attaching one way.
once attached the cover easily hangs the 1.47 LB / 667 gram iPad 3 secure in its magnetic grip..

Step 5: COVER CAN GYRATE

The MAGNETIC  ATTRACTION of the iPad3 for its cover,

Enables the 1.47 LB / 667 gram screen to hang from the magnet coupled nice red leather cover.

Like it ( the screen ) says ;  SEPARATION IS EASY !!

You can see a smudge of magnetic dirt from the regular desert dust storms we experience
in the state Reno Nevada USA where this iPad resides...

The next group of pictures finally explains, the application for the fourteen magnets embedded
in the first leaf of the red cover.

The Leafs are of different widths, so when folded in a triangle back support it is self standing at 75º
or 15º off of the perpendicular and able to sense finger touches on the screen without tipping.

Step 6: ATTRACTIVE MAGNET Features

The embedded Magnets can and do  hold other magnetic items like ;
  • Iron Coins
  • Pad pens
  • Rubber Magnet stock
  • Fridge logos
  • Space Iron Star Stuff knacks
  • Batteries and Resistors
  • Political Buttons
  • A Mystery Component
  • Even a Pen Holder

Thanks for your nice comment  LoL,
I have some very strong NIB magnets that can hold US paper money by the magnetic ink that resides in them.
