That's just head and block. But most moving parts are made of ferrous metals. The better question would be: Is there anything a magnetic plug catches that the oil filter doesn't? My guess is probably not.
However, I was surprised not to see a magnetic plug on either the tranny or differential. The tranny has a strainer filter, but not nearly fine enough to stop metal particles. I'd be more inclined to put one there.
