That argument may or may not be true and really begs the relevant question: Did they know about the potential for strong magnetic fields to move ferrous metal components within their locks?
In addition to features available for the Advanced Series, it features a five-inch multi-touch glass screen in a brushed-metal housing as well as a powered magnetic mount that automatically snaps in once the user holds the device close.
There are two exposed metal connectors, used to pair up with the proprietary magnetic USB charging cable (the only accessory that ships in the box), but the housing appears to be properly sealed.
Physicists thought that ballistic anisotropic magnetoresistance would show itself when a magnetised metal wire a few atoms across was placed in a second magnetic field.
His handwritten field notes show street by street calculations in "chain lengths, " a painstaking process that used metal chains and heavy brass compasses, theodolytes and geodesic transits to reconcile the difference between true north and magnetic north readings.
