=====History and Known Uses=====
The Muggle-Repelling Charm is a common and highly useful enchantment for concealing magical locations and events from the non-magical community. It does not render a place invisible but instead affects the minds of any [[Muggle]]s who venture too close. Known uses in the series include:
  * **[[Hogwarts School of Witchcraft and Wizardry]]:** The entire castle and grounds are enchanted with numerous spells, including strong Muggle-Repelling Charms. As explained by [[Hermione Granger]], if a [[Muggle]] were to look at the school, they would only see a moldering old ruin with a sign reading "DANGER, DO NOT ENTER, UNSAFE."
  * **[[Quidditch World Cup Stadium]]:** The stadium for the 1994 [[Quidditch World Cup]], along with the associated campsite, was protected by Muggle-Repelling Charms to allow hundreds of thousands of wizards to gather undetected. The [[Muggle]] campsite manager, Mr. [[Roberts]], was an exception and required repeated use of the [[Memory Charm]].
  * **[[St Mungo's Hospital for Magical Maladies and Injuries]]:** The magical hospital is located within a "condemned" London department store called Purge and Dowse Ltd. The building is designed to be unappealing, and Muggle-Repelling Charms ensure that non-magical people studiously ignore it.
  * **[[Number Twelve, Grimmauld Place]]:** While principally protected by the powerful [[Fidelius Charm]], the headquarters of the [[Order of the Phoenix]] was also layered with Muggle-Repelling Charms. These enchantments contributed to the local [[Muggle]]s' long-held belief that the houses on the square simply jump from number eleven to number thirteen.
  * **Campsite Protection:** During the hunt for [[Lord Voldemort]]'s [[Horcrux]]es, [[Hermione Granger]] regularly cast Muggle-Repelling Charms as part of a suite of protective enchantments around the trio's campsite each night. This was crucial for keeping their location secret from [[Muggle]]s and any [[Death Eater]]s or Snatchers in the area.
=====Learning and Counter-Spells=====
The specific difficulty of learning the Muggle-Repelling Charm is not stated in the novels. However, its competent and regular use by [[Hermione Granger]] starting in her seventh year suggests it is an advanced but achievable spell for a skilled student, likely covered in upper-level [[Charms]] or [[Defence Against the Dark Arts]] studies.
There is no known counter-spell or method to bypass the charm's effects for a [[Muggle]]. The charm is specifically designed to affect non-magical people, while witches and wizards are immune to its influence and can enter protected areas freely.
=====Etymology=====
The name of the charm is purely descriptive and does not have a known Latin-based incantation.
  * **Muggle:** The established wizarding term for a person born with no magical ability.
  * **Repel:** A verb meaning "to drive or force an attack or attacker back or away."
The name directly and accurately describes the charm's primary function: to repel [[Muggle]]s from a specific location.
=====Behind the Scenes=====
  * In the film adaptation of //Harry Potter and the Deathly Hallows: Part 1//, the protective enchantments cast by [[Hermione Granger]] around the campsite are depicted as a visible, shimmering magical dome. This visual effect represents a combination of spells, including the Muggle-Repelling Charm, `[[Protego Totalum]]`, `[[Salvio Hexia]]`, and `[[Cave Inimicum]]`. (film)
  * The supplementary ebook //Hogwarts: An Incomplete and Unreliable Guide// reinforces the canonical information that [[Muggle]]s perceive [[Hogwarts]] as nothing more than a dangerous, dilapidated ruin. (Pottermore)
