Chapter 2 Electromagnetic Induction Is Not Magical Induction!
"Master Tesla!" Downs bowed excitedly.
"I'm not your master yet. Also, you can call me Wren in the future. Wren waved his hand casually.
"Nope! Whether Master admits it or not, you are my Master, Archmage Tesla. "Downs's prostration is meticulous.
Don't say it, Wren is quite refreshed in his heart.
Suddenly I felt that he was not so uncomfortable as a science dog.
If he hadn't crossed it, he would probably have reached a monthly salary of 3,000 at a young age as soon as he graduated.
Ahem!
Far from it.
As a traverser, when it comes to accepting apprentices, the first thing he thinks of is: I am afraid that I have to give the teenager a nine-year compulsory education first, and then send a box of "Five-Year College Entrance Examination and Three-year Simulation" intimately.
However, for the sake of small money, I will give Downs a crash course.
Folded armor first.
Wren repeated: "Remember! I only teach you [knowledge], as for whether you can learn or not......"
Downs stiffened: "There is no ancient magician in ten thousand. If...... If I really don't have that qualification, I admit it. ”
Wren raised his right index finger with great seriousness: "One semester!" I'll only give you one semester, which is half a year. If you can't learn it......"
Tang Si's heart was awe-inspiring, and he couldn't help but think of the sorcerer's sage in the minstrel to accept apprentices - test qualifications, if the tester does not have qualifications, he will get out immediately, how can he be as merciful as the master, and give him half a year.
Sure enough, Master still values me very much!
Tang Si nodded heavily, and said resolutely: "If the disciple does not make any progress within half a year, the disciple will leave on his own and will no longer interfere with the master's cultivation." ”
Good! The child can be fooled!
Wren finally smiled.
He didn't want to be a liar, but there were too many indigenous fools in the other world, so he had to send him money. He taught physics.
Downs studied physics and couldn't comprehend magic, so what did he have to do with Wren?
As soon as he thought of this, Wren had no psychological burden.
With that, Wren turned around and left, and Downs immediately followed behind: "Master, when will you teach me thunder and lightning magic?" ”
Wren glanced at the sky: "It's getting late, let's rest for the night first, and then talk about it tomorrow morning." Yes, do you know how to cook? ”
"Uh, I understand."
Originally, it would have been an innocent conversation, but as Downs and Wren turned a corner and came to Wren's house, Downs Jr. was stunned.
For the first time in his life, Downs saw the electric light: "Master, this is ......"
Wren was stunned.
Looking at the temporary stupid apprentice with fanatical eyes, Wren found that he was about to lose his explanation.
There are three treasures to cross: cement, glass and soap.
As long as the materials of these three things are enough, they can be rubbed out by hand if they understand the principle.
Glass is plant ash and sand, which is placed in a refractory container and fired at high temperature in proportion, and there can be a glass solution.
It just so happened that there was tungsten in the blacksmith's shop, so Wren used tungsten to pull out the tungsten wire, put it with glass, and made a deteriorated version of the tungsten light cannon, which was connected to the alternating current from the watermill, and made this flickering light cannon.
Before and after, Wren failed to say hundreds of times.
In the face of the natives, this is undoubtedly magic.
Looking at the electric light on the roof of this small tiled house, Downs: "Master, is this also thunder and lightning?" ”
"It's electricity, yes!"
"Where does the electricity come from?"
Wren paused and pointed to the waterwheel not far away: "This is hydroelectric power, referred to as [hydropower]." ”
This time, it was the turn of the stunned Downs.
As soon as he saw Downs's expression, Wren knew that he might be killed, and decisively bit him to death: "Don't think too much!" This is also [science]! ”
The speaker has a heart, and the listener has an intention!
"Science?"
"That's right! This is an application of electricity after electromagnetic induction produces electricity. ”
Wren obviously said it so categorically that there was no doubt about it, and he didn't know what to do, and it became something else when it fell into Downs's ears:
I know! Master is the kind of person who is hard-mouthed and soft-hearted!
He said he wouldn't accept apprentices, but he still accepted me?
He said he was teaching science, but his magic teaching had already begun!
Master is clearly saying now that thunder and lightning are everywhere, and the key is to rely on [induction]!
Master, I see!
……
Here, looking at Downs looking very excited, and a little out of the world, Wren was embarrassed. If he knew that the [electromagnetic induction] in his mouth had been cut into the so-called [induction], he would probably slap this stupid apprentice to death on behalf of Nikola Tesla.
Somewhat confused, Wren asked, "What do you understand?" ”
"Induction!" Downs replied aloud.
Wren was a little unsure, but added: "Okay, I'll show you the solenoid coil tomorrow." ”
Downs blinked. He couldn't understand [Magnetic] and [Coil], which didn't prevent him from continuing to make up for it:
Tomorrow?
Doesn't this mean that Master's test has already begun, and the winner will be decided tonight!?
Downs couldn't help but feel a pang in his heart.
After starting to cook, Downs was a little absent-minded.
After all, his time ...... Not much.
As a former knight's apprentice, Downs is no stranger to this kind of errand. This is how the knights came, the children followed the knights to do chores when they were very young, and the knights would instruct the apprentices in martial arts and teach chivalry when they were free. When the apprentice grew up, he became a knight's servant and followed the knight in battle.
Only by gaining the approval of the lord, or becoming a professional, can you be promoted to a true knight.
Downs quickly helped to light the fire and cook, and nervously answered Master's various questions about the outside world. Not to mention anything else, Downs was extremely sure that Master had really been in seclusion for a long time and didn't know anything about the outside.
His admiration for Master deepened in his heart.
After eating, he still couldn't hold back: "Master, what's the matter with your [electromagnetic induction]?" ”
Wren replied casually: "First of all, you have to have a magnet, the magnet can generate a magnetic field, although the magnetic force is something that cannot be seen or touched, it is real." ”
Wren said as he turned out a magnet and performed the 'magic skill' of magnet to attract the iron.
This scene became a different scene in Downs's mind: Master was reminding me that thunder and lightning were fully present in every corner of heaven and earth before they were seen. You can't see it, you can't touch it, but it's real!?
Here, Wren rotated the U-shaped magnet around a bundle of small coils, and said at the same time: "First form a closed [circuit], and then, as long as the magnet rotates fast enough, it can generate electricity through the change of the magnetic field." ”
Downs' eyes widened: Oh! What Master is saying is that I want to be some kind of 'magnet', which keeps spinning rapidly, and attracts the electricity hidden around me, and as long as my magnet turns fast enough, it can generate electricity that is visible to the naked eye.
Wren saw that Downs was a little stunned, and he couldn't bear it: "Okay, okay, it's tomorrow to teach you scientific knowledge." Let's go to sleep first. ”
In the dead of night, Downs couldn't sleep, tossing and turning, muttering the word 'induction' from time to time.
This small tiled house is only seven or eight square meters, belonging to a half-collapsed house, and there are two people sleeping in such a small place, how could Wren not know the condition of this Han apprentice?
There are many ways to help you sleep.
Maybe it's counting sheep, but in this case, you have to do it another way.
"Downs, don't think too much about it, empty your head. Go to sleep! ”
Master's words floated from him, and Tang Si suddenly became excited.
Master never speaks nonsense, and every word he says must have a profound and mysterious meaning. Even at such times, Master is pointing me out!
Venting?
That's right!
I was so nervous that I ended up with the word "sensing" all over my head, but I couldn't sense anything.
I should follow the teacher's instructions, empty my mind, don't think about anything on my own, and sense the situation in the outside world.
In the distance, there was silence, neither the sound of insects nor the song of birds.
There is only a faint thunder in the sky, and the sound of the wind.
In addition to the beating sound of his own heartbeat, there was a sound that transcended the sound.
Wind and thunder are just appearances.
The real ones are smaller, more ethereal.
But their pulsation is definitely there.
It's light! Very light!
Downs was extremely sure that he had really heard the sound of wind and thunder that was not the sound of wind and thunder.
Could it be ......
This is the legendary [Wind Elemental Sense]!?
Downs' heart jumped with joy.
