Although the gate of the platform was vlised by Dobby so that Harry coukd not enter but as they tried to enter together, Ron was unable to enter as well as Harry. Dobby's spell wasn't specific just to Harry.It just locked the barrier.
Why couldn't Ron and Harry get through the platform?
History. On 1 September 1992, the house-elf Dobby used this charm to block the barrier to Platform Nine and Three-Quarters, therefore preventing Harry Potter and Ronald Weasley from using it, as part of his plot to try to save Harry from the opening of the Chamber of Secrets.
On 1 September 1992, Dobby the House-elf blocked the magical barrier dividing Platforms Nine and Ten in order to prevent Harry Potter and Ron Weasley from attending school.
When it is time for Harry and Ron to go through the wall, the wall closes up and refuses to let them through. They miss the train, and in a flash of inspiration, they decide to follow the train in Mr. Weasley's flying Ford Anglia.
Since Platform Nine and Three-Quarters lies within the range of platforms nine and ten, this is the name that was chosen for it. There's no specific reason as to why this particular fraction was involved, especially when the barrier is directly between nine and ten.
Well you see, in the books we can read that when Lily (Harry's mum) was younger and came to platform 9 & 3/4, her parents was also there; meaning that yes, muggle parents can go there too.
This is something that is explained away pretty well in the series. Ministry employees are on hand to erase/alter the memory of muggles who notice witches and wizards who go to Platform 9 3/4.
Hermione enters the carriage, goading Ron into continuing the spell he was about to do. He recites: "Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow." Unfortunately for Ron, the rat doesn't turn yellow and Hermione instantly shows him up by magically repairing Harry's glasses.
5972 Olton Hall is a preserved Great Western Railway Hall class locomotive made famous for its role hauling the Hogwarts Express in the Harry Potter film series.
so he can tend to get jealous, of Harry in particular, when someone is given the spotlight. We can see this in Goblet of Fire when he doesn't believe that Harry didn't put his name in for the tournament and thinks he just wanted all the glory.
Its founder was the medieval witch Helga Hufflepuff. The emblematic animal is a badger,and yellow and black are its colours. The Head of Hufflepuff is Pomona Sprout and the Fat Friar is the House's patron ghost.
Hagrid was the first person outside the Dursleys to give him a chance. He showed Harry the way of wizardry, of his new life. He even bought all his first-year supplies, including his beloved Hedwig! Besides Ron and Hermione, Hagrid was his first lifelong friend.
For those of you that have ever read a Harry Potter book or seen one of the films, Platform 9 3/4 needs no introduction. For those of you who haven't, this pseudo-fictional location at Kings Cross train station is where the Hogwarts Express begins!
Hermione is tough and independent and Ron is sweet and caring, and they have personality traits and unique qualities that make their relationship work.
Why was the platform closed in Chamber of Secrets?
Chamber of Secrets is the only book where we don't see platform nine and three-quarters at all – Dobby “helpfully” seals it shut to try to protect Harry from harm. Harry and Ron, now firm friends and partners in crime, recklessly decide to get themselves to Hogwarts in Mr Weasley's illegal flying car.
All that was known about 'R' was that it was some nefarious group known as the "Cabal" that was trying to open the Cursed Vaults to acquire some unknown treasure. They claim to value enlightenment and immortality. 'R' seemed to have been manipulating events from during Jacob's school days.
Classroom 1B (also known as the Transfiguration Classroom) is where Transfiguration class is taught. The classroom is located on the ground floor around the Middle Courtyard.
The fascinating Harry Potter platform hidden in London's King's Cross Station is called platform 9 3/4 as it is secretly located between platforms 9 and 10. It's the only place anyone traveling to Hogwarts can catch the express train.
Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow was the incantation of a most likely nonsensical and non-existent spell fabricated by George Weasley that could supposedly change Ron Weasley's pet rat Scabbers's fur colour to yellow, but did not have such effect.
Scabbers was Ron Weasley's pet rat. Passed down throughout the family, by the time he came to Ron, Scabbers was living up to his name with patchy fur and a distinct preference for sleeping.
Hogwarts Castle appears as abandoned ruins to any Muggles close enough to see. Although wizarding society lives for the most part directly alongside Muggles, the interaction between the two communities is virtually non-existent since the International Statute of Wizarding Secrecy was introduced in 1692.
Those who could not prove that they had magical heritage — in other words, any Muggle-born and potentially some half-bloods — were sentenced to Azkaban for having "stolen" magic. Some, however, were apparently released after being stripped of their wands and their jobs, and ended up homeless.
Wizards can make locations Unplottable on a map (and that's without even counting the Fidelius Charm). They have muggle-repelling spells that make muggles see magical things as mundane and uninteresting (Hogwarts), not see them at all (the Knight Bus), or get distracted away from them (the Quidditch World Cup).
