AC voltage from single magnetic pole

[verpies]

In ideal inductor delay will always be exactly 90°.

In the case of a permanent magnet moving inside or across an air core coil, too ?

Point being, you deny the basic law of physics that in purely inductive circuit current will always lag voltage by 90°. This is the school definition of ideal inductor.

I heave never read a definition mentioning a lag between the induced current and induced voltage in an inductive circuit. Do you think this is because I dropped out of school too early?

Do you realize how idiotic it is to deny this.

Yes and if you are right that the induced voltage leads the induced current in a coreless inductor/coil that is subjected to a varying external magnetic flux from a permanent magnet moving inside or across that coil THEN I will send 1 Bitcoin (1 BTC) to the account of your choice.

How much will you send me if I am right ?

Last few posts you started dodging by grabbing onto air core coils... in desperate hope that phase shift doesn't apply to them...to your dismay, it does. Here is some a-level physics for you, core or no core...

The circuit which contains only inductance (L) and not any other quantities like resistance and capacitance in the circuit is called a Pure inductive circuit. In this type of circuit, the current lags behind the voltage by an angle of 90 degrees.

Use that bitcoin for basic electronics course, it might do you well.

Don't change the subject. It is not about that.
Air core (or coreless) coils are just simpler to discuss as they are devoid of secondary phenomena such as the magnetostriction, which you've mentioned and which I do not want to deal with.

You are avoiding answering my questions again. (Hint: they can be identified by the question marks at their end).


Let's try with another one:
Q: Does that a-level physics statement, you just quoted above, apply to an inductive circuit which is subjected to an external varying magnetic flux from a permanent magnet moving inside or across the inductor in that circuit and to the lead/lag between the induced voltage and induced current in it ?  Core or no core.


Simple "yes" or "no" will suffice.

I really would like to send it to you if you are right.  You will have earned it with your time and energy and dedication to the truth in science ...and I still have plenty more for a basic electronics course that will help me not to mislead the users of this forum.

How much will you send me if I am right ?






EDIT:
_{By now, it is obvious to me that my arguments, no mater how cogent & logical, will not change your entrenched position, so I have to ask: What would constitute a proof for you?
-Would a judgement by a higher authority constitute a proof for you?
-Would empirical evidence coming from someone else constitute a proof for you ?
Do tell us, what would you accept as proof in the 1BTC challenge ?}

I'm not changing the subject, you are, dodging in all (im)possible ways.

You are avoiding answering my questions again. (Hint: they can be identified by the question marks at their end).

Not avoiding, it's just that you still hope this LAW somehow does not apply if voltage is induced by moving magnet. I see desperation also amplifies attempts at sarcasm. To your dismay...

Simple "yes" or "no" will suffice.

...it does. Completely irrelevant if voltage is brought to the inductor from external circuit or induced by changing magnetic field, in ideal inductor current will always lag voltage by 90°.

There are many preschool level electronic courses online for free, those are best suited for you and you can save that bitcoin for a candy.

OK, thank you for replying directly. Now your position is clear.


For the record, I indeed think that this "law" about the i&v lag does does not apply when the voltage is induced by the moving magnet.

If I am found wrong about this, I will take all these preschool level electronic courses and I will apologize publicly for every false and confused statement, that I have made in this discussion and I will promise that I will not mislead the members of this forum anymore. I will also rethink my life and realize that my mind is loose and unable to reason coherently and that I am biased, dishonest and unable to let go of my cherished preconceived notions and that I have been full of myself and overly confident and suffering from the Dunning-Kruger effect all this time.

If I am found wrong, then I will really send you the 1 BTC - don't worry, I still have more for these preschool-level courses.
How much will you send me if the result is opposite?


So what would constitute a proof for you?
It is obvious that arguments from me will not suffice, no matter how cogent and logical I make them...
