 Magnetic-radiation detectability at a marginal far-field distance

For a harmonic magnetic dipole observed with kr of order unity, its quasistatic, induction and radiation fields scale as $r^{-3}$, $k{r}^{-2}$ and $k^2{r}^{-1}$ and need not be cleanly separated experimentally. The radiated-power law remains an asymptotic flux statement, but $P/(4\pi r^2)$ alone does not specify the local detected field. Detectability further depends on directional pattern, plasma propagation, antenna coupling, bandwidth, integration and noise. A tiny nonzero vacuum radiation term does not by itself establish either a practical detection or an absolute impossibility.
