I just started reading the series again a week ago, and am just starting Chamber of Secrets now (I work full time and don't always want to read when I get off work, so in the past week I read the first book in two sittings), and was just thinking about it after reading the first chapter, thought it'd be for a nice discussion: Does anyone else wonder why the ministry thinks Harry cast the spell on the cake, causing it to levitate and then fall? I mean, you'd think if they are able to tell when someone is using magic when they shouldn't be, that they would know if it is or not. I mean, in Sorceror's STone when Hagrid comes to get Harry in the cabin an uses his umbrella to light a fire and give Dudley the pig tail, that this sensor would have gone off since magic was used near an underage wizard or whatever.
I don't know, for a book series like this, which I love an have read many times, I start getting nitpicky with the etails like that. Was it ever explained or not in any of the books or by J.K. Rowling herself?
Well, I think the Trace only traces where the magic is done. In the hut in PS Hagrid did magic and he was a full-grown wizard, so they can't blame Harry of doing it. But in CoS when Dobby did the levitation charm, Harry was the only wizard in the area. The Trace doesn't trace House-elves.
Spoiler:
Now that I think about it, the Ministry made the same mistake with the trace as Voldemort did with the boat in the Cave. Interesting
I think its because the trace does not trace muggles. I really doubt they'd think that muggles were out on that little island...so they wouldn't care if magic was done there. they had no way of knowing an underage wizard was there either. just that magic was done on a tiny remote little island. _________________
