Interesting point! Thanks!!!
Yes, it is attracted but only a little bit. The original still has the nickel (very old and oxidized). The 5 microns or so do generate a very slight pull but not enough to lift it like on the newer ones. I will however check the plating thickness... it could be much thicker on the new stuff and that would definitely explain the difference.
Need to think of a way to do the test without stripping it...
BTW, the weight is also very different... the original is noticeably lighter.
I doubt the weight difference can result from a few extra microns of nickel plating.
I'll look into it and post the results soon (-;
