Some advice:

Your advice is not needed,as most of the time it is incorrect--as in this case  !again!

If you are going to post a diagram, and least try to have what you see in the diagram make sense.  In your diagram the output waveform shown does not match the physical setup shown,

Once again-either you did not read description in post as to what the diagram is showing,and/or cannot read the description on diagram it self.
The diagram clearly state's,and shows- EMF will equal 0 when magnetic flux through L1 is at maximum. The diagram clearly shows that the magnet is at the closest point to the coils core,and there for the magnetic flux through the core will be at it's maximum. At that point,the wave form clearly shows the 0 volt point of that wave form at the output of the coil-the only reason the wave form was included.

it's a mistake

Most of what you have said on this thread is a mistake,so i am not really to concerned when you make another-as above.

Indeed I am being somewhat picky here

I would say more a need to continually harass me,as you did not like me proving you wrong on so many occasion's.

The problem is that often enough you are dealing with people that don't understand what is going on and therefore they can easily be misled and confused by confusing graphic images that have errors in them.

There are no errors on the diagram--just your need to try and scale your way back out of the hole you dug your self.

Is there anyone else that had trouble relating my diagram below in conjunction with this post to EMJ ?.
That is also correct. And if we use a PM generator,the EMF produced from the stator coil will be 0 when the PM is directly at the center of the stator coil's core

Goodness, your response need only be 180 degrees as per your original answer or 90 degrees based on the references you cite. 

Perhaps you believe it to be something else altogether...

You still Dont Get it, you truely dont get it...

Of course Brads Circuit as was shown will be ±90 Degrees. The issue here is as I have stated some 20,000 times now but youre incapable of reading it... is that the Prediction that TK reffered to is incorrect, it still is and you, you idiot are supporting that!!!

Faraday's Law of Electromagnetic Induction, with Heinrich Lenz's Contribution,


PREDICTS E.M.F  -   NOT CURRENT AND NOT THE MAGNETIC FLUX

CAN YOU READ THAT ?

You just dont get it!!! Youre brain is still in bed!

PW, seriously now, youre wrong, youre never going to admit it, never going to concede and will continue to play Dumb Dumb and run off on wild random Claim Chases of your wildest fantasys.

I hope I have done a good job of making it clear for you to be able to start your learn to read classes... Start with Sight Words... Its how they do it these days.

See, admitting being wrong was not that hard after all.  I am proud of you... 


Now, using Faraday's law which states that the induced voltage is directly proportional to the rate of change of the magnetic flux, would it not be logical to predict that when the rate of change of the magnetic flux is at a minimum, the induced voltage will also be at a minimum?

PW - You and TK are wrong!!!

Brad even proved it in his last video. You have incorrectly inerpreted Basic Science 101 for preschoolers.

I am not wrong, but you believe in your fairy tales...

   I can see this as becoming known as the "Junkie-Tinman Law"

Are you and MH related monnie?-i mean minnie
I see you skipped out on answering the simple question about induction
