I have always been taught that electrical and magnetic RF fields

and vice-versa.

The ratio of the E-field to the H-field is the impedance.
For free space, the characteristic impedance is 377 ohms.
For a small loop antenna, the H-field is much greater than
the E-field and the impedance is very small. Presumably,
in a superconducting loop, the E-field is zero and all the
energy is contained in the H-field. I wonder if we will
ever have superconducting ham antennas?
