Arthur Weasley is the head of the Misuse of Muggle Artefacts Office, and works with a wizard named Perkins. Amongst other jobs, the Misuse of Muggle Artefacts Office delivers reports to the Auror Headquarters on Muggle artefacts that relate to cases they are investigating: Mr Weasley is asked to provide a report on flying Muggle vehicles, to aid with the investigation on Sirius Black.
A small, dingy room, the Misuse of Muggle Artefacts Office is located at the end of a shabby corridor on the second level of the Ministry of Magic. Two desks are crammed inside the office, which is smaller than the broom cupboard next to it, and overflowing filing cabinets line the walls. The little wall space in the office showcases Mr Weasley's fascination with Muggle artefacts. On top of Mr Weasley's in-tray sit several enchanted objects, including a toaster that hiccoughs, and a pair of leather gloves that twiddle their own thumbs. A photograph of the Weasley family stands on Mr Weasley's desk, although Percy appears to have walked out of it. There is no window in the office.
