And maybe (I don't know nothing about magnets) the fact that their magnet are very close to other silicon chips inside the MacBook AND the LCD display (It's LED, but technically they're almost the same).

Magnets in laptops aren't a problem - spinning disc hard drives have strong magnets in them.

And yet Apple has a patent on it…

Not sure what to make of that.

The patent office will grant you a patent on $anything, as long as you add "...on a computer" or "...on the internet" or "...over a cellular network".
