Muggles kan fortfarande orsaka att magiken fungerar i några av dem.
Förtrollade föremål som faller i Muggles händer och visar magi i Muggle-ägandet är anledningen till att ministeriet har en Misuse of Muggle Artefacts Office.
“He works in the most boring department,’ said Ron. ‘The Misuse of Muggle Artefacts Office.’
‘The what?’
‘It’s all to do with bewitching things that are Muggle-made, you know, in case they end up back in a Muggle shop or house. Like, last year, some old witch died and her tea set was sold to an antiques shop. This Muggle woman bought it, took it home and tried to serve her friends tea in it. It was a nightmare – Dad was working overtime for weeks.’
‘What happened?’
‘The teapot went berserk and squirted boiling tea all over the place and one man ended up in hospital with the sugar tongs clamped to his nose. Dad was going frantic, it’s only him and an old warlock called Perkins in the office, and they had to do Memory Charms and all sorts to cover it up …” - Harry Potter and the Chamber of Secrets, Chapter 3 (The Burrow)
Flyga mattor anses vara en "Muggle Artefact" så en Muggle kan troligen "använda" dem.
Arthur Weasley förklarar till Barty Crouch Sr. att flygande mattor skulle vara förbjudna enligt lagen som förhindrar trollkarlar från förtrollande Muggle-objekt.
“Oh, and I’ve been wanting a word with you, too, Arthur,’ said Mr Crouch, his sharp eyes falling upon Mr Weasley. ‘Ali Bashir’s on the warpath. He wants a word with you about your embargo on flying carpets.’ Mr Weasley heaved a deep sigh. ‘I sent him an owl about that just last week. If I’ve told him once I’ve told him a hundred times: carpets are defined as a Muggle Artefact by the Registry of Proscribed Charmable Objects, but will he listen?” - Harry Potter and the Goblet of Fire, Chapter 7 (Bagman and Crouch)
