[Harry Potter] Is there a black market for magical objects in the Muggle world? Are there any government agencies that try to use magical artifacts to their advantage without wizards' knowledge?

Well, there's an entire ministry department that deals with magical artifacts in the muggle world (which Arthur Weasley is part of). A black market for such would he harder, though - any muggle with a known connection to magic would be *obliviated* as soon as discovered. And it's much easier to discover who muggles are when you have magic.
