First, a loop isn't "good for mag fields" any more than a dipole, and a
dipole isn't any more "good for E fields" than a loop. See my posting of
about 3 days ago in this newsgroup in the thread " Loop vx Folded
Dipole noise factor".

Second, the E field isn't 120 * pi stronger than the H field. In free
space, in the far field from the source, the E field is 120 * pi OHMS
times the H field. You could say one is stronger than the other only if
they had the same units, which they don't. A parallel to this would be
to say that the voltage is "stronger" than the current in a 10 ohm
resistor, but "weaker" in a 0.1 ohm resistor. Voltage and current are
different things, just as E and H fields are, so can't be directly
compared for "strength".

You might want to dust off the fields text you used in your EE
curriculum, and review the relationship between E and H fields, and what
happens when they interact with an antenna.

stronger than the mag field, why is there any consdieration to
using a loop antenna?
This question has gnawed at me since my EE course work, but
nobody seems to have a situation where the mag field is better
to receive.
