... why lead though? I don't think lead generally sticks to magnets?

I mean unless you meant lead for some particular reason, that doesn't really matter and this comment just becomes useless nitpicking (and by becomes I mean always was), but I'm trying to justify making this comment to myself, and I come up with the justification that I really don't understand why you picked lead.

Is it because of the density?

My guess is he just wasn't thinking about that, so he made an error.
