Taken from wikipedia, "If several turns of the wire are made, this becomes where N is the number of turns..." when speaking in terms of flux linkage and coils of a wire. However, in terms of a straight conductor (e.g. transmission lines), flux linkage for a meter long straight conductor has units of Weber-turn/meter, what is this weber-turn referring to? Basically, it's throwing me off because there aren't any turns. Is it essentially just the same as N = 1 in terms of a straight conductor? Thanks for any input.
