Why is there no attenuation in the magnetic field at the boundary of the near field?
That PDF provides various 1/distance^N contributors to field strength.

The Efield has [1/D^2 - 1/D^4 + 1/D^6]

The Hfield has [1/D^2 + 1/d^4]



I recall similar equations in Corson and Lorrain. I ain't a trained E&amp;M jock, just trying to understand the mechanisms of shielding for reliable 16 and 24 bit systems.
