> Paramagnetism/diamagnetism doesn't apply to "magnets"

I also said "objects" in the GP to this post. There is no paramagnetism or diamagnetism in vacuum. You need an object made of an appropriate material. I would not insist on calling such an object a "magnet" if there is an objection to that.

However, what is described in the article is a kind of permanent magnetism; the term "magnet" applies to that in any case.
