I am curious about wire size for rewinding rf coils. It seems that the primary wire size is smaller....e.g. #38 vs. the secondary wire around #32 awg. This seems counterintuitive and I was wondering why. What is the principle involved here? I presume it is not a' step up or step down ' relationship, or is it??? And sometimes it appears that the wires are the same size for both primary and secondary sections.
