Huang Shaoze's newspaper clippings about ghosts hitting the wall, it still doesn't seem to make sense for us to use here, because once we have a compass in our hands, we won't lose our way, and secondly, we haven't seen any markers that can disturb our vision, and there is no possibility of confusion!

I told everyone the conclusions I had reached, and everyone nodded after hearing this, Huang Shaoze smiled secretly and said, "How can you be sure that your compass is still working normally!" ”

I was stunned when I heard it, and I couldn't help but glance at the compass in my hand: "My compass...... No problem! ”

Then I walked up to Wen Chengyu and compared my two compasses, and the magnetic needles in the compass were pointing in one direction.

The monkey looked at it and said, "In my opinion, it should be fine!" Everyone has seen it, even if it's bad, their compasses can't be broken at the same time! ”

Huang Shaoze's expression did not change after hearing this, and then said: "Let the two of them watch after a certain distance!" ”

I couldn't help but be stunned when I heard this, could it be that the direction of the compass changed when I changed places? If that's the case, then the compass is still hairy!

Although I was puzzled, I still did it, so I deliberately walked out with my back to Wen Chengyu for nearly twenty meters.

I stared at the compass in my hand as I walked, and it turned out to be an incredible scene...... It happened!

I found that as I walked forward, the magnetic needle on the compass was actually deflected! And it seems that the farther I get from Wen Chengyu, the greater the angle of the magnetic needle deflection!

At first, I thought it was a deviation caused by the vibration when I was walking, but when I stopped, the position of the pointer when it was still was at least 10 degrees different from before!

It is obviously not normal to have such a large deviation in such a small range!

Everyone also came to compare the pointing of the two compasses at this moment, and the deviation of ten degrees also attracted everyone's attention.

The monkey also showed a blank expression when he saw it: "Hey, I said, what the hell is going on, if you look at it this way, at least one of their compasses is a bad Luo?" ”

"What do I mean...... Not a compass! Huang Shaoze said lightly.

"Not a compass?" When the monkey heard this, he asked, "Didn't you just say that their compass was not working properly, and you don't remember your own words?" ”

"It's really not a compass problem!" Wen Chengyu suddenly answered, looking at his appearance, he seemed to understand something. He glanced at Huang Shaoze, and then said, "It's a problem with the magnetic field!" ”

"Magnetic field?" When I heard this, I couldn't help but chuckle.

Wen Chengyu continued: "At this moment, our compass may no longer be within the influence of the geomagnetic field, and the space we are in at the moment should have another magnetic field."

"Not bad!" Huang Shaoze nodded when he heard this, it seems that he and Wen Chengyu thought of going together, and I probably guessed what was going on after he reminded him.

Speaking of magnetic fields, we have to mention how the compass works. The earth is a large magnet, and the compass is affected by the magnetic force in the earth's magnetic field, so it will guide at one end and point north at the other. As long as it is not affected by other magnetic fields, the pointing of the compass will always remain the same at any location on the earth.

However, at this moment, the magnetic needle in the compass has deviated, indicating that there must still be a disturbing magnetic field around us!

However, the generation of a magnetic field requires conditions!

I remembered that I learned in high school physics class that magnetic fields do not arise for no reason, and in our current situation, there are only two possible scenarios: first, the mountains here contain magnetic mineral deposits; Second, near here, there is an electric current generated, because electricity generates magnetism!

I immediately told Huang Shaoze and Wen Chengyu of my idea, and they both agreed with me, and we both felt that the first scenario was more likely, because it was still relatively common for the mountains to contain magnetic deposits.

The monkey couldn't say a word after listening to us for a long time, and when he saw that we had finally finished speaking, he began to shout: "Hey, I say, what have you been talking about for a long time?" What magnetic field is not magnetic, does it look the same as a football field? ”

I almost didn't laugh when I heard it, in order to alleviate the panic and anxiety of everyone for days, I wanted to take the opportunity to tease the monkey, and said with a smile: "Look, you don't listen to you when you are told to study more, you don't even know what we are talking about at the moment, and now you know that you regret it!" This magnetic field is ......."

When the monkey heard that I was making fun of him for not graduating from elementary school, he seemed to be a little unhappy, and before I could continue, he interrupted my words: "Yes, don't explain it to me, people like me who haven't graduated from primary school don't understand what you say, and you don't rarely hear it, don't waste your time, you just say what we should do now!" ”

There was a slight dissatisfaction in the monkey's words, and I thought for a while and said, "Now, we have to find out the root cause of our loss of reverse, and we have to break this ghost wall!" ”

"Don't follow me all this nonsense, be specific!" The monkey asked.

"Specific...... Aren't we thinking about this? ”

The monkey rolled his eyes at me when he heard this, and said: "Look, you cultural people haven't come up with a specific plan for a long time, so you still show off this magnetic field football field in front of my monkey master, I thought that you cultural people can solve any problem in minutes!" ”

I was speechless by what the monkey said, I was teasing him, but he choked on nothing to say, and he was quick to fight back.

Everyone was happy when they saw it, and when I saw that my purpose had been achieved, I immediately said to the monkey, "Okay, okay, I'm not going to quarrel with you, I'm wrong!" ”

The monkey didn't understand my affection, and rolled his eyes again and said: "Hey, don't mind, who is your little marquis, how can it be wrong, it is we who are rough people who stir up your cultural Yaxing'er!" ”

When I heard it, I was anxious: "Damn, you dead monkey, you really got on the shelf with me!" ”

"How dare I, we rough people......"

"Okay, two!" Huang Shaoze said with a smile on the side: "You two are really a pair of living treasures!" ”

As soon as I heard this, I immediately said to the monkey, "Okay, let's stop arguing with you, let's get down to business!" ”

"Who wants to fight you!" The monkey rolled his eyes at me again as he spoke.

……

After a hiccup, we got back to business.

At this time, Wen Chengyu began to walk around with his compass, and it could be seen that he was looking for the law of the magnetic field here.

After changing places at random, he came back to us and looked at him as if he had discovered something. I only heard him say: "Alas, you see, the magnetic needle is deflecting every time I change places, which means that the direction of the magnetic field is different in each place, and combined with the fact that we have circled around a lot and then circled back, it means that the direction of the magnetic field in various places is connected, and it should be a circle!" ”

Huang Shaoze nodded again and again when he heard this: "Not bad!" That's the reason! He paused and continued, "But if this magnetic field is generated by magnetic deposits all over the mountain, then this magnetic field should be chaotic, and the direction should be chaotic!" ”

At this point, I already understood what Huang Shaoze meant, and then asked, "What do you mean, do you mean the magnetic field here...... Not caused by magnetic deposits in the mountains? ”

"Hmm!" Huang Shaoze nodded and continued: "It is impossible for magnetic ore to produce such a regular magnetic field!" ”

"Could it be...... It's the second case/" I also questioned my conjecture a little: "No! Over here...... How could there be a deposit of current zài! ”

"But there's no other explanation!" Huang Shaoze paused and continued: "If this magnetic field is really generated by an electric current, then according to the relationship between the current and the magnetic field, it can be inferred that at the center of this magnetic field, there must be a current perpendicular to the magnetic field!" ”
