There is no electrical field associated with a static magnetic field. Any change of position or intensity of the magnetic field will result in an electrical field and an electromagnetic wave (wavelength dependent upon rate of change). Any transmission of information implies changing the field in some way.
2 - A cruise of the whitepapers indicates that the magnetic field strength is related to distance via 1/d^6, as opposed to radiated power, where it's relatd to 1/d^2. This means a much sharper dropoff in power... meaning the point beyond which there is a negligible power level is much sharper.
1/d^6 is sharp drop, and I'm wondering what they're doing. 'Magnets' doesn't explain it. A magnet does inherently have a dipole field (which has a sharper dropoff than inverse-square drop of a monopole field), but 1/d^6 sounds like a higher order field than that, which is interesting. I assume from the article that they've been using magnetic inductors rather than electrical conductors to construct and detect this particular electromagnetic field, which is also interesting.
