'Electromagnets' are very important for the development of earth technology, although it is not crucial, but without electromagnets, the earth technology would never be so developed.

However, the discovery of the 'electromagnet' is also inevitable, magnetism and electricity are inseparable, and the connection between electricity and magnetism is closer than anyone thinks, and 'electromagnetic induction' is not only applicable on the earth, but also in the world of Assatom.

At the beginning, the maid confirmed through research that the world of Assatom does indeed have 'electromagnetic induction', and the intrinsic connection between electricity and magnetism is very significant, so after arriving at the Sad Wind Realm, people will start to study the 'generator'.

In the world of Assatom, magic is the 'root', the 'root' of all things.

All objects have 'demonic conductivity', and theoretically everything can be called 'magical materials'.

However, there are very few magical materials that can be used to make magical objects and magic circles with excellent 'magic guiding properties', and even if the maid really realizes the idea of 'magic energy machinery' in her mind, the output is still a big problem.

The machine she built at the beginning still needed a mage to carve magic circles and runes when it was manufactured, which meant that it could not be automated.

Although there are a series of reasons such as the machine tool cannot process the magic materials and the machine tool is not intelligent enough, the machine tool will continue to develop according to this idea, and the machine tool will still not be able to process the magic materials in the future.

Magical machines are still 'mechanical' after all, but the energy they rely on when they run is magical energy.

By inputting mana into the magic machine, the magic circle inside the machine will be activated, and after the mana flows through the power part and enters the control part, the magic energy machine can be used.

However, herein lies the problem, the magic energy machine only uses 'magic power', and there is not much difference in essence from those machines on the earth that use electricity, the difference is only a slight difference in the internal structure.

The maid wanted the magic machine to be able to process the magic materials, so that the magic machine could be mass-produced, even if there was no mage waiting around, the magic machine itself could carve a magic circle and runes.

However, in order to mass-produce magic machines, a large amount of magic materials is required.

Today's magic energy machine has only one machine tool, but in the future, there will be more than one 'machine tool'.

Maybe the mage can replace the work of cranes and shield machines at this stage, but it is impossible for all this kind of work to be done by mages in the future, this is too stupid and a waste of human resources, if it is not for the fact that the development of the Principality of Sorrow needs to do this now, the maids will not let the mages do these things.

The mage was still doing research when she was best at it, but in order to speed up the development and construction of the principality, she had to send the mage to work in those positions - that was supposed to be the work of a worker!

The larger the machine, the more magic materials are needed to produce it, but the number of magic materials is far less than the number of ordinary materials.

If it's steel, they can produce as much as they want, but magic materials can't!

Until now, the magic materials in the world of Assatom have been obtained from 'nature', and many magic materials cannot be cultivated artificially, except for naturally produced magic materials.

The situation is similar on Earth, but in addition to the materials that nature itself has, earthlings are able to make the materials they need to make electrical equipment, even if the materials themselves are 'synthetic'.

Here's the problem, magic materials are 'natural', no one has ever tried to synthesize them, even if it's a secondary processed magic material, it's itself a magic material.

The number of magical materials is not large, and in the world of Assatom, the proportion of magical materials is much lower than that of ordinary materials, whether it is wood, metal, or strange things.

This is also a matter of course, but it restricts the development of magic energy machinery.

If this problem cannot be solved, then magic energy machinery will always be only used in production, and will not help much for the modernization of society.

Due to the scarcity of magic materials, the corresponding items will also be expensive, just like the maid's vision of the 'faith network communicator', that kind of equipment also needs to use magic materials in the production.

As a result, this kind of thing is not widely available at all, and the price of items related to magic is still high, which is too different from the future she envisioned.

So, to solve this problem, she was thinking.

After leaving all the business to Edith, Serena calmed down and thought about it alone.

She thought about it for a long time without any result, but as winter approached, and the knights returned with the elven slaves they had saved, Cervantes followed suit.

He moved much faster than the knights, and there was no need to fight, and the nobles knew what to do.

If it weren't for the elven women who were delaying him, he would have returned long before the knights returned to the principality.

As soon as he returned to the principality, he heard about it and gave his thoughts on it.

"Sela, remember what you mentioned about the 'electromagnet', right? Electromagnets can only be used in a few places because they are the only ones that need electromagnets, but the magic materials are different!"

"What we're missing is magic materials, not magic. ”

"Injecting magic into a material doesn't make the material itself magical, because the very existence of a magical material means that it has a stable internal circulation structure, which we can't do, at least not right now. But what we can do is to use some materials that are good at magic conduction, but cheap enough to 'put together' the 'magic materials' we need - for example, copper wire, we need a certain property of a certain magic material, so we study the results of the internal circulation of that magic material, and use copper wire to build a ...... 'thing', treat that thing as a whole, and then inject magic power, activate it, so that maybe we can get a cheap replacement?"

About these things, Cervantes's inherited memory does not tell about it, because the dragons don't need this, they only need to rely on their own powerful bloodline, their blood already contains magic, and it can even be said that their blood itself is a flowing magic.

He didn't understand this, but just guessed according to his own ideas, whether it would succeed or not was still a question.

Rather, it would be a big problem if it succeeded, because it was just one of Cervantes's messy ideas.

Still, it's a try.

Although it is just an idea of the black dragon, there is no other way to do it anyway, if it can be done, then they will make a lot of money.

“...... That's a good idea. ”

Ziegler also praised the idea when he heard it.

Lately, he has been obsessed with reading, and after reading the books given to him by the maid, he has a lot of unfulfilled ideas in his mind, but the output of magic energy machinery is a big problem.

After hearing Cervantes's idea, he also felt a little itchy and thought that he should participate in this research.

Whether they can succeed or not is not a problem, if they can't succeed, they can find another way out, but if they can succeed, then let alone the mass production of magic energy machinery, they can even directly carry out the mass production of magic energy machinery overnight.

'Copper' is not a magic material, but it has a low price and relatively good magic conductivity, if the idea of the black dragon can be realized, then it can overcome the constraints of 'magic material processing' and directly face the problem of 'enchantment processing'.

However, this is not a difficult problem to solve, just like when the maid first made the magic energy furnace, at that time she had already mastered the technology of mechanized production of magic circles, but it was not mature and expensive.

If this idea can be realized, then many problems can be solved at once.
