Zhu Youzhen drew a model of the dry battery and explained it to Xu Yin in detail.

Xu Yin looked at it seriously for a while, he didn't expect his majesty to design such a battery structure so quickly, and even thought about what material to use instead, and couldn't help but be very excited:

"Your Majesty's intelligence, Wechen is far beyond his reach, Wechen didn't expect to think of doing this."

"It's nothing, even if I don't tell you, you can figure it out if you figure it out yourself, because you've already figured out the principle, it's just a change of material."

Saying that, Zhu Youzhen said: "But the current created by the battery is still limited, and it cannot be used for lighting or other purposes for a long time, and the voltage generated is not large. ”

"Your Majesty, please advise," Xu Yin said.

"The way you make voltage now is by chemical reactions, but the basic principle is still that the gains and losses of electrons produce voltage to form currents, in this case, in addition to chemical reactions, you can think about whether there are other ways to make matter transfer electrons."

Zhu Youzhen took out a compass as he spoke: "You should already know by now that magnets have positive and negative poles, like this compass, and electricity also has positive and negative poles, haven't you thought about any correlation here?" ”

"I've thought about it, and someone in Nanjing's "Nature" run by Ms. Li Xiangjun has published an article about this, saying that after the positive and negative poles of electricity appear, the effect of magnets repelling and opposites attracting each other can appear."

Xu Yin replied.

"Very good, it seems that even if I don't intervene, someone in Daming will be about to discover the generation of electricity."

As soon as Zhu Youzhen said this, Xu Yin couldn't help but ask curiously: "Your Majesty said that electricity generates magnetism?" ”

"Nature is possible, not only electrical energy generates magnetism, magnetism can also produce electricity, you have now discovered the magnetic induction line, use iron filings to simulate the magnetic induction line, and in fact, these are the magnetic fields formed by magnets, the magnetic induction lines of the magnetic field are his manifestations, electricity is the same, it also has an electric field, otherwise the positive and negative electrodes will not attract each other when they are close to each other;

That is to say, the electric field may also have electric induction wires, if the electric field can be generated by voltage to create an electric field, a metal device can produce a magnetic field and magnetic inductance lines, then, if a metal rod is used to cut the magnetic induction line, the magnetic induction wire will be used to transfer the electrons on the metal rod, thereby generating current, you can try, if it is successful, you can use mechanical power to cut the magnet to generate electricity, and there is no need to send so much energy to make any battery. ”

How Faraday used the phenomenon of electromagnetic induction to create electricity, thus inventing the generator, Zhu Youzhen does not know.

Now he can only tell Xu Yin what he knows, and with Zhu Xuesen as a pseudonym, he ordered someone to package this knowledge to "Nature", let it be released, and let people who are interested in the empire participate.

Naturally, Xu Yin was also involved, and while summarizing his experimental records of making dry batteries and electric lamps, he began to prepare to verify the theory of magnetic energy generation and electrical energy generation of magnetism.

Xu Yin didn't know who Zhu Xuesen was, and why he first proposed the electromagnetic induction hypothesis in Nature less than three months after His Majesty told him about the theoretical knowledge.

Because there is no experimental argument, it is called a hypothesis.

But even the hypothesis has attracted widespread attention in the Ming Dynasty scholars, and many similar properties of electricity and magnetism have made many Ming researchers begin to doubt what the two have in common.

Nowadays, as soon as this hypothesis comes out, there are naturally many people who discuss it and prepare to do experimental verification.

There are even capitalists with a background who have begun to discuss whether it is possible to use steam mechanical power to cut magnets to generate electric current if the hypothesis is true, so that many products related to the use of electricity can be manufactured at low cost.

These forward-looking capitalists sniffed out the wealth and began to spend a lot of money on research.

But in the end, it was Xu Yin, the genius of the Ming Empire who was best at constructing circuit experiments, who first proved the hypothesis of electrical energy generating magnetism.

Then, because Xu Yin did not explore how to use magnetism to generate electricity like Faraday, he directly used Zhu Youzhen's suggestion to use metal cutting to discover the current, thus demonstrating the hypothesis of magnetic energy generating electricity.

For a time, Zhu Xuesen and Xu Yin became the most hotly discussed figures in the Ming Dynasty academic circles.

But Zhu Xuesen has always been the head of the dragon and does not see the end, so Xu Yin has naturally become a frequent speaker in major university halls.

The Daming Manufacturing Bureau founded by Zhu Youzhen instructed Han Shoujing to hire Xu Yin as an engineer of the Manufacturing Bureau, and began to ask Xu Yin to organize a team to use this principle to manufacture generators and motors.

Of course, despite the theory and experiments, generator manufacturing is still not so easy to build.

Xu Yin still needs to spend a lot of time thinking about how to design the generator, how to ensure that the generator is effectively generated, and also has to consider the problem of manufacturing costs.

It will take at least a year or two for this to come down.

Fortunately, Zhu Youjian instructed the Daming Manufacturing Bureau to fully cooperate, even if he spent more money.

Therefore, Zhu Youzhen believes that the first generator of Daming should be available soon.

It is worth mentioning that dry batteries were quickly manufactured and quickly mass-produced.

The company controlled by Zhu Youzhen's royal capital contracted the production of electric lamps and dry batteries, so that Zhu Youzhen also made a lot of money in it, but Xu Yin also made a lot of money, because on the surface, he was the one who owned these patents.

Electric lamps were soon used in all walks of life in the Ming Dynasty.

First of all, the steam locomotive no longer needs to burn candles for lighting, and the large arc lamp and large battery can meet the lighting use of the steam locomotive when it starts at night, so that the steam locomotive can pass at night and improve the domestic trade speed of the Ming Dynasty.

Secondly, folk lighting began to be replaced by electric lighting one after another, at least in the era when electric lighting and candles coexisted.

Especially the rich and noble, naturally do not care about the cost of dry batteries, and began to use electric lamps as a symbol of noble status, but also so that in the early stage, although the manufacturing cost of electric lamps is not high, but the price is very high, otherwise it is not enough to show the status of rich and noble people, and the more expensive the better.

As a result, the company controlled by Zhu Youzhen's royal capital made a lot of money.

And Xu Yin also became the second richest man after Yang Mingshen, which is another person in Daming who became the richest man in Daming after the railway.

Therefore, it has inspired more people to join the ranks of sacred studies and promote the development of Daming's manufacturing industry.

The Forbidden City also began to use electric lights, and the lanterns were naturally eliminated, and many times they could only be hung as auspicious objects, and Zhu Youzhen could finally see his concubine's white body at night, and there was no need to touch it anymore.

Because of this, Daming's nightlife is also richer.

Electric lights are always easier to create more brilliant light than candles, especially after the invention of colored lights, which makes people's entertainment life more beautiful.
