"An Imperturbable Charm is used to create an invisible barrier around an object."
— Description[src]

The Imperturbable Charm (incantation unknown) was a charm that created an invisible magical barrier around an object, such as a door.[1][2] Objects would bounce off of the barrier, and it also muffled sounds.[1] An object enchanted in this manner was said to have been "Imperturbed".[1]

History

During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Bill Weasley taught this charm to sixth year students in Defence Against the Dark Arts class as part of his extra-curricular evening lessons in the subject.[3]

"It’s no go with the Extendable Ears, she’s gone and put an Imperturbable Charm on the kitchen door."
Ginny Weasley regarding Molly Weasley's use of this charm at 12 Grimmauld Place[src]

In 1995, Molly Weasley used this charm on the kitchen door at 12 Grimmauld Place to prevent the children from eavesdropping on Order of the Phoenix meetings using Extendable Ears. Ginny Weasley was taught by Nymphadora Tonks how to test if something had been Imperturbed by flicking Dungbombs at the suspected target and seeing if they bounced off.[1]

Behind the scenes

In the film adaptation of Harry Potter and the Order of the Phoenix, this charm is not used on the kitchen door, and because of this Fred, George, Harry, Hermione, Ron, and Ginny are able to eavesdrop on the Order of the Phoenix meeting that took place on Harry's first night at 12 Grimmauld Place.

In the book version of Harry Potter and the Prisoner of Azkaban, obstacles are said to get out of the way of the Knight Bus, suggesting that it may have a similar charm placed upon it.
