do you believe that Ferrari, Dolivo-Dobrovolsky, Tesla and many others during their work on the construction of the generators and motors had in their heads the Faraday's law? It's ridiculous.

I assume that you are talking about the electrical engineers who design the electrical motors that go into electric cars?

Having done an electrical engineering course (including introductory subjects on power engineering), I can assure you that they are taught Faraday's law.

Modern designers would use modelling software which incorporates Maxwell's Equations (which combines the findings of Gauss, Faraday and Ampere). And the software models real magnetic materials and real heat flows.
See: https://en.wikipedia.org/wiki/Maxwell%27s_equations

As for having Faraday's law "in their heads", after a while working with a set of equations, it does become somewhat intuitive; effectively your brain can model what is going on, even before clicking "Start" on the simulation software. That's what allows the human to tweak the design to find the optimum solution with the materials at hand.

It’s even taught in secondary school physics and as @evan_au says, it becomes intuitive, second nature.

Mikhail Dolivo-Dobrovolsky is the father of the electric generators and motors from the end of the 19th century. He and the others have nothing to do with electric cars.

Almost everyone who goes in school is taught electromagnetism, including Faraday's law, but that doesn't mean that the law is true.
The designers work on the basis of trial and error method, not on the basis of mathematical formulas.
Besides, the Faraday's law in the textbooks is mostly "demonstrated" (nowhere is demonstrated live) by a rotating loop in a magnetic field. There is no generator in reality that works on this basis. All generators work on the basis of a rotating magnet.

I also claim that in the famous rotating loop no current is induced at all.
Please see "What type of current is induced in a wire loop which rotates in a magnetic field?"

What does it mean "becomes intuitive"? It means nothing to me. Through the explanations of mine the things become consciously comprehensible. Isn't consciously comprehensible what I am talking about in the just linked thread?
Also in this: "Is the explanation of working principle of synchronous generator and motor true?" https://www.thenakedscientists.com/forum/index.php?topic=78617.0

Yes, it is. But although you perfectly understand what I am talking about, you can't get used to the shock that the whole theory of electromagnetism is ruined. A new theory is coming, whether someone likes it or not.
Nobody can stop the truth.

They didn't give a toss about the theory. They wanted to make something that works and left the theory to the theorists. They were surely no theorists.
GG: In basic engineering school and also in technical HS classes, Faradays laws was experimented with millions of times in the past. It is just basic electrical theory. AC generators are interesting. The current flow for a resistive load is in phase but if you have an inductive load is shifted by 90 degrees lag. The same is true of a capacitive load but the shift leads.

Would you like another guess?

What does it mean "becomes intuitive"?

It means something, which was not initially "intuitive" becomes so through use.
Anyone who has used some bit of obscure knowledge until it became familiar  would understand this.

It means nothing to me.

That tells us something...

Thus far, you have shown that there's a poorly drawn diagram in a textbook.

"Poorly drawn diagram in a textbook", LOL.
It is a poorly drawn diagram in millions of textbooks all over the world through a whole century.
The error is not accidental. It is a consequence of the Faraday's law of induction.
It is certainly not the end of the civilization. But it is the end of the indisputable authority of the "Big brother" called "Science".

[Origin]

Is Faraday's law of induction true?

Yes
When a new motor or generator is designed it is first modeled, one of the principle aspects of the model is Faradays law.

I have shown much more than that, but you are too biased and you cannot admit it.
Here is one thing: although we have powerful computers today, this mankind has never really understood what is "one" and what is "zero" on physical level.

Not, apparently, on this site where you have mainly posted nonsense.

I can't quite follow your thought, but I can say this: I have denied the Faraday's law with arguments presented in my original post and in this post of mine "What type of current is induced in a wire loop which rotates in a magnetic field?" https://www.thenakedscientists.com/forum/index.php?topic=78515.0

You and the others "deny" my assertions only by saying that I am wrong.

How was the Faraday's law experimented with millions of times in the past? Was it with a wire loop which rotates in a magnetic field? Have you ever seen this experiment live? I don't think so. If someone has seen it, let him put it on YouTube. There, on YouTube, I see only animations, nothing more. Until I see this experiment live, I will consider it only as a thought experiment which is still not carried out in reality. If someone has the means to carry it out, let him also connect it to an oscilloscope. Let we see what the oscilloscope will show, since I claim that no current will be induced in the loop.

There is no phase shift neither in synchronous generators nor in motors. Phase shift has nothing to do with that we are talking about here.

[Bored chemist]

"Consciously comprehend" is a level higher than "become intuitive".

No, it is not.
It's like driving a car.
You start off having to carefully concentrate on each action but, after a while, it becomes "automatic" and you can do it almost without thinking.
So, once again, on the facts, you are wrong.

Worse than that, you are conceited enough to try to argue about meanings of words after you already said you don't know what they mean.
How dumb is that?

[Bored chemist]

I did it at school
Youtube didn't exist at the time.

The experiment confirmed Faraday's law.

Can you imagine the fun we would have had (as students) if the experiment hadn't confirmed what the teacher had said?

What did you see?

[Bored chemist]

An alternating voltage on an oscilloscope

What would you expect me to have seen?
How would what you expect differ from what Faraday's laws say?

Homopolar generators usually use rotating disc.
