wrote: As far as I can determine, "magnetic loop" (often shortened to "magloop") is a term strictly used by amateurs. It came into popular use something like 15 or 20 years ago. The name enhances the widely held mistaken belief among amateurs that it responds only to magnetic fields. I've seen the term "magnetic probe" or "magnetic antenna" in the EMC community to describe such antennas because of their near field characteristics. Hello, Roy. The use of "magnetic probe" for a small loop(s) intended to sniff out induction (near) fields from a radiating structure seems appropriate. But using "magnetic antenna" for a small loop that is to be used as a far-field receiving antenna just doesn't make sense, IMHO. Ditto for a transmitting antenna. In the case of the receiving antenna, my hunch is that all this came about because the plane of the loop when aligned with the H-field vector of an incident plane wave produces maximum current in the loop.
