... just how strong the magnetic field is, for it to affect the hard drive of a computer at any likely distance. It seems like metal objects would be flying through the air and sticking to the floor. Also, I have to wonder how a static magnetic field would affect most phones. Seems there would have to be an alternating field of some sort to do so. Finally, any links to the 'numbers' (field strength, gauss, whatever the proper term is)?
