The limits to what magic can achieve in the Wizarding World have been shown through Voldemort's use of dark magic. However, the Harry Potter series is far larger than the Dark Lord's activities, and there are rules to magic that can't be broken. The Ministry of Magic keeps tabs on certain aspects of magic, while other areas are either not fully understood by wizards or are better left alone due to the danger involved.
J.K. Rowling has also revealed vital details about the Wizarding World outside of the book series. All in all, it's worth learning more about the rules of magic in the Harry Potter series to understand how life works in this universe.
A Muggle Can Perish If They Try To Do Magic With A WandPhoto: Harry Potter and the Sorcerer's Stone / Warner Brps. Pictures
Albus Dumbledore was very polite when he refused Petunia's request to enroll at Hogwarts as a child. As it turns out, Dumbledore was also protecting Petunia's life, as Muggles can't handle wands. Not only do they lack the inherent magical ability, but Muggles are also in danger if they take hold of wands.
Should a Muggle get their hands on a wand and try their hand at magic, something violent will happen at the cost of their lives. Wands are meant to be carried by wizards, and even then they are loyal to the ones they choose. Muggles are in danger if they handle wands, as the magical devices are not meant for them.Never knew this before?
Dark Wizards Who Attempt The Patronus Charm Will Be Killed By Their Own WandsPhoto: Harry Potter and the Chamber of Secrets / Warner Bros. Pictures
Raczidian was a dark wizard who lived in a castle surrounded by dementors and grew to have control over them. His dementors were driven out by a hero known as Illyius through the use of a Patronus charm. Raczidian had never witnessed a Patronus before and considered it a spell of immense power that he wanted to use.
Unfortunately for Raczidian, he learned the hard way that a dark wizard is incapable of casting a Patronus. Raczidian's attempt resulted in his wand sprouting out so many maggots that they covered him entirely until the maggots devoured Raczidian whole.
Raczidian is an example for all dark wizards about the extent of magic they can use, with Voldemort and his Death Eaters also shown to be incapable of casting a Patronus.Never knew this before?
Ghosts Only Get One Chance To Move OnPhoto: Harry Potter and the Sorcerer's Stone / Warner Bros. Pictures
Nearly Headless Nick expresses some regret to Harry for his status as a ghost in The Order of the Phoenix. He doesn't know if he will get another chance to go into the afterlife; the truth is that it isn't possible. A witch or wizard is given a choice at the moment of their death to move on, which is a one-time offer.
A person doesn't get the chance to turn back should they decide to become a ghost, meaning they're trapped as an echo for all eternity. The permanent state of a spirit is proven through the Bloody Baron and the Grey Lady, who are ghosts from a thousand years ago.Never knew this before?

Harry wonders why the Wizarding World isn't filled with ghosts after Sirius's demise. Nearly Headless Nick tells him that Sirius has moved on and won't be coming back. Nick doesn't know why a person doesn't return and, in truth, it comes down to a wizard's personality.
A witch or wizard needs to be in a state of regret or fear to become a ghost - happy people don't fit the requirement. Many have speculated on the possibility of Fred Weasley returning as a ghost, but Fred was a brave person who would have accepted death rather than be saddened by it. Fred even smiles in his last moment, ruling out any possibility of him as a ghost.
Magical people can return to Earth, but those who feel they have lived fulfilling lives won't do so. Characters like Moaning Myrtle and Nearly Headless Nick were sad in their last moments or lived depressing lives and moving on scared them.Never knew this before?
