a certain scientific harry potter
Page 283
What Harry was going to do was the kite experiment. He had also inquired about a series of relevant information before, so he naturally knew that the Russian scientist Lichman was unfortunately struck by induction lightning and died when he was replicating the kite experiment. !
Moody, an old psycho, dared to jump out and interfere with Harry's experiment. Of course, Harry wouldn't kill him directly, but he would have to suffer a little bit, so don't come here to make things difficult for others!
So Harry came up with the plan.
In fact, it’s useless for Lao Deng to bring more people to support him. Hogwarts professors usually rarely have metal products on them. In addition, Harry can secretly manipulate the wind element. in the insulating state.
In this way, the jug in Moody's clothes will inevitably trigger the induction thunder, and he will be unable to take care of himself directly!
"Just because of a jug? Harry, you have known Alastor for a long time, why didn't you remind him before?"
Dumbledore's tone seemed to be complaining. After thinking about it for a long time, he still felt that this might be Harry's revenge.
"How do I know, he didn't put down the jug?" Harry rolled his eyes angrily, "When thunder strikes, don't get close to trees, and try not to carry metal objects on your body, these are things that any ordinary child knows When Professor Moody first arrived, he dispelled the lightning for safety reasons, how could I know that he didn't even know this kind of common sense?"
"You..." Dumbledore was once again at a loss for words when he heard the words. It involved ordinary people's scientific knowledge. No one at the scene could compare with Harry, even Old Deng was equally speechless.
"Professor Moody... God, I didn't expect you to be injured so badly! This is really a regrettable accident~" After easily clearing himself of suspicion, Harry enthusiastically drew out his wand, "But don't worry I will definitely heal you..."
"No need!" Who knew, just when Harry was about to release the medical magic, Moody sat up from the ground as if on a spring.
"It's just a small injury, I'm fine at all, I don't need you to treat me!" He waved his hands in a panic, and even managed to prop up the broken prosthetic leg, and quickly moved into the castle.
"Albus, I'll go back and rest by myself first!"
After hastily greeting Dumbledore, Moody's figure disappeared at the end of the auditorium in embarrassment, as if something bad would happen if he stayed for a while.
(ps I didn’t expect that today’s chapters are so appropriate. It rained heavily outside Sanmiao’s house before, and all kinds of sparks and lightning directly chopped the nearby power lines, and it’s only recovered now. Then I just went online and found The hot words of the Chinese Academy of Sciences artificially induced thunder, if you are interested, you can also search for it, the scene is very shocking~)
Chapter 590 Three Can't Control, That's Dangerous
"What are you doing, you don't want to be treated? Are you really angry?"
Seeing that Moody was stumbling, but wanted to run away, Harry couldn't help being speechless for a while.
It was just that he was struck by lightning, so what?
It's fine for you to jump out and be a monster with me, and you can't accept it if I fight back. Can this still be played?
To be honest, Moody's behavior reminded Harry of some people he had met before.
That’s the kind, he can scold you all you want, but if you scold him the other way around, it’s like killing his whole family, you’re an old glass heart~
However, Harry actually wanted to study the physical signs of wizards after being struck by lightning.
He just roughly felt that Moody's magic power seemed to be extremely short, and he didn't know if it was due to the consumption of resisting damage, or there were other reasons.
Unexpectedly, this old man would come up with the idea of "hidden disease and forbidden medicine", so Harry could only temporarily press the idea of opening another academic research.
And the other people at the scene can finally cheer freely at this time!
"Great! Harry, you succeeded!!" Professor Bubbaji was the first to jump out, dancing like a child.
She was the first to know that Harry was going to attract thunder and lightning, and now she finally waited for this day.
When Moody blew up the kite, Professor Bubaji was extremely depressed and thought that today's experiment might only end in failure.
But immediately afterwards, Harry used a more shocking, even mythical method to bring her a huge and incomparable surprise!
When she saw Harry standing proudly in the night sky and 'grabbing' the lightning with his bare hands like a god of thunder coming into the world, she really fell into uncontrollable excitement!
Muggle studies... No, it should be general social cognition, this course is definitely going to be popular!
Looking at the equally excited eyes of the students around him, Professor Bubaji knew that the newly revised General Social Cognition course would definitely become a hit among Hogwarts students in the future!
"It's a wonderful experiment, Harry." Professor Tofty also applauded at the same time, "Although it is only for a moment to light up a Muggle light bulb with lightning, it has already been able to prove that lightning and Muggle electricity exist. Great connection. And you also showed another major discovery, that is, lightning can actually kill dementors!"
"Thank you for your compliment, Professor Tofty, but the purpose of my experiment this time is to prove that the lightning in the sky and the electrical energy used by ordinary people are essentially the same thing." While thanking the other party for his affirmation, Harry smiled He shook his head apprehensively, "So, if you want, we can continue the experiment. What I'm going to show next is some lightning bolts I stored during the thunder just now, and they can also be used to light up the light bulb. In addition , I can also demonstrate the artificial creation of lightning."
"You...what did you say?!" Professor Tofudi was shocked when he heard the words, "Harry...you said you can make lightning?!"
"Of course~" Harry nodded with a smile, "Although the power is definitely not as powerful as real lightning, I guarantee that you will believe that it is definitely lightning once you see it!"
"Really? Then you start right away, I can't wait to see how you make lightning!" Professor Tofty's eyes lit up suddenly, he didn't expect Harry to have something hidden treasure!
It's just that, unlike the excitement of most people present, some people obviously don't want Harry to continue.
"Harry, how about this is the end of your experiment?" Dumbledore interrupted Professor Tofty, who was in agitation, and stepped forward to stop him, "You have already completed the experiment of attracting lightning, although the process was indeed shocking. , but the danger is obvious, and Alastor was even injured. Therefore, in my opinion, the next experiment should not be continued..."
"Mr. Principal, I can guarantee in my own name that the next experiment is absolutely safe! In fact, if Professor Moody hadn't forced me to temporarily change the experiment plan, the previous kite experiment would have been safe!"
Harry raised his head and looked at Dumbledore, his blue pupils were constantly constricted because of sullenness: "And as far as I know, wizards are risky when conducting any spell experiments. Hogwarts conducts experiments every year. In the apparition test, there are not a few students who were seriously injured due to split body, but the test has never been interrupted because of this! So..."
"Harry, Professor Tofty is still waiting." Suddenly, Hermione interrupted Harry.
She moved to Harry's side in the name of a reminder, and at the same time tugged on Harry's robe indiscriminately: "Shouldn't it be time to take back those bottles you put outside?"
"Alright, then let's continue the experiment."
Being reminded by Hermione, Harry also remembered the current situation.
After all, it was the first day of school, and Harry always wanted to give old Deng a little face.
Otherwise, he really would have blurted out just now.
So... Anything that you, Albus Dumbledore, cannot control must be dangerous, right!
"Professor Tofty, let's go back to the auditorium."
Using the Flying Charm to retrieve more than a dozen Layton bottles that had been placed in advance, Harry did not argue with Old Deng, but walked into the auditorium with Professor Tofty.
Behind him, a group of enthusiastic students rushed in.
Actually, Harry didn't care about Lao Deng's stop, because these students were not the subjects he wanted to show, so if Lao Deng couldn't get angry, he could just force everyone to go back and rest.
But Lao Deng didn't do this, so Harry didn't care about turning the experiment into a public class.
After returning to the auditorium, Harry used the wind element to blow out most of the candles in the room, leaving only a few sporadic ones in the corner.
The dim candlelight danced indistinctly, and the atmosphere of the scene suddenly became mysterious.
"The items in front of me are called Layden bottles, and they are devices that can store electricity. Before this experiment, Professor Tofty has conducted a detailed inspection on them and confirmed that there is no charge on each of the Layden bottles. "
On a long table directly in front of the auditorium, Harry lined up all the Leiden bottles, and everyone's eyes seemed to be attracted by a magnet, moving back and forth with his movements, for fear of missing them every tiny detail.
"But just now, because I put these Leiden bottles outside, after the lightning ended, they have stored a tiny part of the lightning. At this time, if I want to release the lightning stored in the bottle, Then it can be done like this!"
While everyone was watching, Harry leaned the metal rod that matched the Leighton bottle towards the body of the bottle. When the ball at one end of the metal rod was about to touch the metal ball at the top of the Leighton bottle, an electric arc suddenly jumped. out!
Nourishing~
There was a small crackling sound from the Leighton bottle, but it was very loud in the auditorium where everyone was holding their breath.
And that flickering and jumping arc is even more clearly discernible in the dim environment!
"It's Lightning!" A student suddenly stood up and shouted, "Harry Granger bottled up Lightning!!"
hum!
In the next second, the entire auditorium suddenly became noisy again.
Chapter 590 Artificial lightning, Muggle 'magic'
What kind of response will you get if you conduct a scientific experiment in the magical world?
Harry can now say responsibly that the response is absolutely super strong.
Especially the electrical experiment he is doing, which is definitely more mysterious than magic to almost all the teachers and students in the school.
However, Harry understood their behavior, because he had felt the same way when he was in high school.
Otherwise, people often say that if junior high school physics is a natural science based on theory and practice, then high school physics is a proper metaphysics~
I personally demonstrated the discharge process of the Leiden bottle, and let everyone see the obvious electric spark... Just by showing this hand, a large number of people at the scene began to believe that the bottle contained the previous lightning .
However, Harry's performance was only just beginning.
"The one just now was just a simple discharge. In fact, the lightning in the Leiden bottle can also be used to light the bulb."
While explaining, Harry took out another lamp bead with positive and negative pins connected in advance, and held it close to another charged Leiden bottle.
Of course, what Harry prepared was actually a semiconductor light-emitting diode, the so-called LED, but wizards would not understand the difference between this thing and an incandescent lamp.
For them, this thing is the lamp used by ordinary people, the kind that can be turned on when the electricity is turned on.
So when the LED lamp beads lighted up, there was another exclamation at the scene.
"This is just a very simple discharge experiment. It does not require magic to participate, and it is also without any danger." Harry smiled and invited the professors in the audience, "Professor Tofudi, Professor Bubbaji, you are interested If so, you can come and try it yourself.”
"Can we too?!", "That would be great!"
The two professors whose names were called ran forward excitedly. At first, they thought that what Harry was doing was so complicated, but after trying it out for themselves, they found out that they just need to put the lamp bead close to it, and it can be turned on. Bright!
Although it was only for a moment, the two professors were sure that the lamp bead must be electrified!
And the source of those electricity is undoubtedly the lightning just now!
"There are still a lot of Leiden bottles left. If you are interested, you can come and try."
There were about ten electrified Leyden bottles, and Harry simply gave the students a chance to play.
At this moment, the entire auditorium was boiling, and a large group of people raised their hands to ask for a try, which made the experimental equipment, which was considered to be relatively rich, all of a sudden become overcrowded.
The Weasley brothers took the lead in snatching a Leighton bottle by running fast, and successfully lit the lamp beads; among the students of the Eagle Academy and the Badger Academy, several students also got a chance.
In addition, there is little Dennis who just entered school today, he is holding up the lamp bead that has just been lit and giggling, and his brother Colin has been taking pictures of him non-stop.
"Hmph, it's just a light, what's there to show off?"
"That's right, even if there is really lightning in that bottle, there's only a little bit of it that can't do anything at all!"
Of course, discordant voices will never be lacking anyway. In Hogwarts, the group of people headed by Slytherin is definitely Harry's unswerving dark all his life.
However, every time they jump, they are just showing their ignorance.
"If you want the light bulb to stay on all the time, you only need to have a closed circuit." Harry casually took out the battery pack and light bulb that he had demonstrated to Professor Bubbaji before. The son suddenly ran out of words.
That big light bulb was really on all the time, and it was far brighter than any candles and oil lamps in Hogwarts!
"The one who was worried about the lack of electricity just now, do you want to replace this light bulb with yourself, I promise you won't become like Professor Moody~"
"Oh, no need... really no need!"
Seeing it from a distance with Harry's gloomy eyes, the student from the Snake Academy who was clamoring before immediately withered away.
Cut, it's just a coward.
"So, it's not your fault that you're mentally retarded, but it's your fault to show off."
To be honest, Harry actually understood the students of the Snake Academy quite well. After all, before he entered the magic circle, these self-proclaimed aristocrats always had a sense of superiority. How could they be trampled on like this?
However, it was their business that they felt good about themselves, and if they jumped out and took the initiative to owe Harry, it was purely looking for trouble.
Harry is not their ancestor, and there is no need to let them get used to it, just slapped him with a big mouth, simple and clear.
After successfully quelling the storm that wasn't a storm at all, Harry, like Tinker Bell, took out the props that needed to be displayed at the end of this experiment from the suitcase, the induction generator.
When preparing for this experiment, Harry actually thought of... It is possible to generate electricity in Hogwarts.
Although the magical force field here is strong enough to shield all electromagnetic-related phenomena, making many electronic devices unusable, and even alternating current cannot be introduced, this does not mean that it is completely impossible to generate electrical charges in Hogwarts.
Electricity is also generated by frictional electrification. Even if the magnetoelectricity is shielded, it can still use electrostatic induction to 'generate electricity'.
Thus, there is the current induction motor.
After all... when it comes to simulating lightning, there's nothing better than the phenomenon of point discharge.
After putting the device in place, Harry began to shake the handle quickly, and the electric plate of the induction motor also began to rotate rapidly, persistently transferring the charge to the left and right Leiden jars.
And soon, between the two discharge forks at a similar distance, a crackling and jumping blue arc was suddenly pulled out!
