In which direction or directions does an electrically small loop (less than 1/10 wavelength in circumference) have nulls in its radiation pattern?

An electrically small loop antenna (less than 1/10 wavelength in circumference) has a distinctive figure-eight radiation and reception pattern. The maximum signal reception occurs in the plane of the loop (off the edges), while deep nulls—points of almost zero reception—occur broadside, or perpendicular, to the face of the loop. This broadside null is extremely sharp, which is exactly why small loops are favored for radio direction finding. By turning the loop until the target signal disappears into the null, the operator can precisely determine the line of bearing to the transmitter. Distractors claiming nulls are in the plane of the loop describe the exact opposite of how small magnetic loops actually behave.
