Yes, a magnet is attracted to both stainless (non ferrous) steel and ferrous steel, but not to the same degree. The magnet will be attracted to the stainless steel very weakly and the ferrous will show a much stronger attraction. It is a very noticeable difference.
Just for general info. The Campagnolo catalogs of the 1960s and 1970s show the bare derailleur cable housing is to be used at the rear derailleur and at the bottom bracket. The would be "the company line."
In the 1970s a lot of the riders I knew (myself included) used colored plastic covered brake cable housing for the rear derailleur cable housing so as to match their brake cable housing. Very commonly done.
Yes, I too would rather ride my bikes than talk about them.
