I will be doing an oil change today and sending off some oil for analysis, been doing so for the last 25,000 miles. Heres a thread with a report way back:

I've been thinking of using a megnetic sump plug, but realsied that the ferrous magent types arent terribly strong, neodynam would be beter. An old hard disk died on me a few months back and i removed the 2 neodynam magents from it. I'll attach one to the back of the sump plug and the other to the base of the sump plate next to the plug.
So heres my question/problem:
If you look at the link above, you'll see that there is a fair bit of zinc, magnesium, boron and calcium......... my understanding is these are oil additives. If so, wont they be attracted to and held by the magnet, as well as the harmfull wear metals, instead of circulating round the engine doing whatever (protective) thing they do?
I've actually done a further 3 oil analysis' since the above post, heres a link to the latest report:
