What exactly is this idea you're talking about?"
One type of electromagnetic projectile is called a coil gun. It uses the force of an electromagnet to attract metal to accelerate a metal projectile and shoot it out. I think that if we can imitate that, we can shoot out metal at high speed.
What do you mean? It's true that electromagnets attract metal, but when they pass by, they try to pull it back, so it doesn't accelerate after all."
'The moment it passes by, you turn off its electromagnet. Then, turn on the electromagnets in front of the turned-off electromagnets and accelerate the projectile with their magnetic force. If you repeat that, theoretically you should be able to accelerate the projectile to sublight speed, which is close to the speed of light.
If electricity is converted to magnetic force to accelerate the projectile, there would seem to be a lot of energy loss."
No, with living magic, the D-particles can be converted directly into magnetic force, so there should be little loss. And since power on/off can also be solved by
I was convinced by Métis' explanation. ＜If the magnetic force only works backward with
Let's build it and try it out."
Once again, start up the Sage system and form something like a rifle barrel with D-particles. Give that barrel
The magnetism is generated from ten points on its magnetizing barrel, which is adjusted so that it only takes effect behind the interior of the barrel.
After making it that far, we headed for the underground practice area. The projectile was a five-inch nail. It was a nail about 15 centimeters long.
We decide to test-fire the concrete block in the underground practice area as a target. When I activate the new magic, a magnetic force-generating barrel about 70 centimeters in the air floats in the air.
A five-sided nail is inserted into the magnetic force-generating barrel, which is already generating magnetic force. At that moment, a sharp metallic sound is heard and a five-sided nail pops out from the tip of the magnetic force generating barrel.
A five-sided nail flew to a concrete block about ten meters away, and its tip pierced about five centimeters.
This tale has been unlawfully lifted from Royal Road; report any instances of this story if found elsewhere.
When magnetism is generated from ten locations, it is this powerful? Now let's see if we can double the number of magnetic points.
At Metis's suggestion, we built a magnetic force generating barrel with twenty magnetic generating points and tried it out.
As before, when a five-sided nail is placed in the formed magnetic force-generating barrel, it shoots out invisibly fast and pierces the concrete block.
This time, even the head of the nail bit into the concrete.
I think I could take down an orc or two."
This is not good enough. The opponent is a basilisk zombie.
'Well, yes. How much do you think we should extend this magnetizing barrel?"
Let's say it is five meters long and has an inner diameter of eight centimeters. Let's say the length is five meters and the inner diameter is eight centimeters.
I said, "All right. Let's say there are three hundred magnetic generating points."
'Then you'll need a dedicated shell.
I decided to have it made at a factory of a friend of mine. The material is steel, the shape is a cannonball, and the size is about that of a 350ml plastic bottle.
A few days later, I headed to the Narukami dungeon to test fire the shells and the new magnetic force generating barrels that I had completed. Arriving at the second level canyon area, I decided to test-fire in a corner of the area where not many adventurers go.
He decided that the area was a place where a number of small hills existed, and where he did not have to worry about involving other adventurers if he tried his high-powered magic.
Beside me, Elmore is keeping a watchful eye on the surroundings. Because we may encounter a wyvern.
There are no demons in the vicinity."
Okay, let's give it a try."
When the new magic was invoked, a magnetic force generating barrel with an outer diameter of 10 cm, an inner diameter of 8 cm, and a length of 5 meters appeared. Floating just at shoulder height, the magnetic force generating barrel looks like a pipe made of ice, probably due to the high density of D particles.
The reason why the density of D-particles is actually visibly increased is because it consumes such a large amount of D-particles. It takes that many D-particles to generate a strong magnetic force from 300 locations in this magnetic force generating barrel.
I moved the magnetism-generating barrel fixed in the air a little, aimed it at a nearby small hill, and then inserted a shell made of steel before magnetizing it. A high-pitched metallic sound was heard and at the same time the shell was fired.
A shockwave was generated near the tip of the magnetism-generating barrel, which spread around and blew me and Elmore away.
Yikes."
As he rolls on the ground and tries to get up, an explosion occurs in the small hill he was aiming at. The earth and sand about two hundred meters away exploded and rose into the air.
Why did it explode?"
I was surprised that the explosion was caused by a shell that had not even contained gunpowder and had only hit the target.
It is the same explosion that occurs when a meteorite falls. The tremendous pressure and high temperature generated when they collided at very high speed seems to have caused the explosion.
The scale of the explosion can be inferred from the fact that a crater of about 15 meters in diameter was created. It seems to be powerful enough.
The magnetizing barrel is gone."
I thought they just spontaneously disappeared over time."
It's not time for it to disappear yet, since we've given it
After discussing this with Métis, we were able to estimate the cause. We concluded that the high-pitched metallic sound generated when the shell was fired was caused when the shell scraped the inside of the magnetically generated barrel, damaging it. The damaged barrel could no longer maintain its shape and disappeared.
We had thought that the magnetically generated barrels could fire about several shots in a row, but this was an unexpected event.
It's going to be difficult to keep the shells from coming in contact with the magnetizing barrels."
"And the shock wave that occurs when it is fired must also be addressed."
I let out a sigh. This magic is as powerful as the weapons installed on warships, which is why it seems to be so difficult to handle.
How is the magic consumed?"
When Metis asked me a question, I took out my magic counter and measured.
It's more like 20 percent of the total magic. Not as much as a railgun, but it consumes a lot of magic."
Although not yet completed, we decided it was time to decide on a name, and decided to call it "Projection Barrel.
