Magic is not real. Nobody can do anything by "a magic spell".
In a given fictional world, magic spells may be able to do some things and not others; you'd have to be more specific to get answers about, say, whether such a thing could happen in the Harry Potter universe or not (but not from me; I neither know nor care about the Harry Potter books).
The spell used in the movie, Practical Magic, was fictional. It was created by the imagination of the author and has no basis in fact. I believe you can find the wording in the original book. A resurrection spell from one of their aunts old magic book.
Aparecium This spell was mostly used to make invisible ink appear, but it could be used on items in general. Was mentioned in the books when Hermione was trying to make something appear in Tom Riddle's diary (CoS)
The first magic shown in the movie is Dumbeldor using the put outter.
The spell "Petrificus Totalus" is a petrifying spell. If someone cast "Petrificus Totalus" on you, you would freeze up and be unable to move or make sound, though you will be consciously aware of what is going on around you. It is very different from a Stunner, which knocks you out completely.
Harry's signature spell is Expelliarmus, which causes the enemy's wand to be knocked out of their hand. He likes using it because it only disarms them instead of hurting them giving Harry time or causing the enemy to back-off.
become a baby diaper by a spell
That is the correct spelling of "diaper" (aka nappy).
train magic with defence+magic spell and a staff
No there is not. Spells and magic do not exist in the real wold
No. Mermaids do not exist and magic spells are not real.
Diaper
No one can give you an example of a magic spell and have it work. Magic does not work and people can not become mermaids. Mermaids are not real and people can not change into them.
Magic is fake. So there is no spell on you and no one to lift it.
No. Spells and mermaids do not exist. You cannot physically change what you are.
Enchant: to cast a spell over someone or something with magic. Enchantment: the state of being under a spell or magical influence. Enchanter: a person who casts spells or uses magic to enchant others.
Spell cards and Magic cards are the same. The reason for the confusion is because Magic cards were changed to Spell cards during the release of Magician's Force.
There is no spell that can make you a 'wizard'. Male practitioners of magic also call them selves witches. To be a witch one must have years or knowledge of their craft and have the wisdom to not misuse it
