Ah, yes. A "magnetic" loop antenna as opposed to an "electric" loop
antenna. Funny, but none of my seminal antenna books (Kraus, Jasik,
Terman, etc.) mentions such a beast. A visit to the above website
indicates that W2BRI is referring to an electrically small loop (he
recognizes this), which is the customary term for the type of device being
described. That an electrically small loop behaves as a magnetic current
element does not qualify the use of "magnetic" in its name, IMHO. Radio
waves are electromagnetic by nature - you don't transmit or receive
exclusively radiated electric or magnetic fields. Sincerely, and 73's
