With a pair of screened loops and a whip it is possible to receive
separately the magnetic and electric fields associated with a radio signal
and to record their strengths at different locations. This can reveal
significant differences on account of building and electrical clutter, but
only if the loop is adequately screened. No myth!

What you describe is a direction finding system with a general antenna
that can be switched in to sniff for a transmitter to take a bearing
on. A commonplace design for this application. The loops are no more
screened than any other, and careful observation of their construction
details would reveal the necessary break in the screen which serves
for balance only. Any claims to magnetic field separation are, as
Mark well put it, a myth.

The only way you could achieve this separation is by traveling at the
speed of light with your antenna in that magnetic field, at its 90
degree peak to the electric field null. This reduces the topic from
the status of myth to that of absurd.
