Magnetic fields within a toroid inductor.

[MileHigh]

The posting below is primarily about you and I don't want to interact with you, period.

I can relate to the detractors and enemies schtick too.

I have had people say to ignore all my postings because I am supposedly an extremist.  I have had people relentlessly bash me for days and days and days, picking apart anything I say trying to twist it into something bad.  People that personally attack me over and over.  People that say that I am "polluting" the threads.  I once tried to explain to someone how to test their transistor because after two years of building pulse motors the only thing that he could do was make sure the wire lengths were equal. (??)  Then that person had a total freak-out on me and went ballistic.  I have been bashed over and over because I don't show any bench work yet in my educational and professional life I have spent literally thousands of hours on the bench.

And the ironic thing is that with good intentions and without malice I am simply trying to tell people the truth and I try sometimes to educate them.  I am not perfect and I can't always speak in politically correct prose so as to not offend someone that in reality has no clue whatsoever about what they are trying to do.  It's too easy to claim that you have a fragile ego and cry that you are being belittled when in fact that's not the truth.  When I sometimes make a really good suggestion the response is mute silence.  If a beginner that barely knows what he or she is doing makes the same suggestion, they are heaped with praise.

What irks me the most is the peer pressure among the forum members themselves.  I coined a term for it, "Orwellian stagnation."  If an outsider comes to the forum with a crazy proposition many people will challenge the person.  But if an insider to the forum makes a crazy proposition, then in the majority of cases nobody will say anything.  And I have seen things posted on this forum by insiders that are ridiculous and counter-productive for people that are trying to learn something.

The bottom line is that I will stand my ground.  Anybody that thinks that I am a "bad guy" because I speak the truth to the best of my abilities is wrong.  This notion that I am "demeaning and belittling people" is driven by the ego issues of others, because I don't consciously make an effort to demean and belittle people.  On the flip side, I have seen many people consciously and maliciously demean and belittle me - without merit - and it all stems from their own frustrations.

You indeed have to have a thick skin sometimes.  I have no problem having thick skin.  But if somebody is going to maliciously and relentlessly go after me and try to make my life miserable I will push back.

You stay the fuck away from me.

The YouTube user Lasseviren1 is a science teacher and was gracious enough to post about 200 videos covering physics, dynamics, electrostatics, electricity and magnetism, etc.

That's where the clip I posted about the toroid's magnetic field comes from.  The guy is great and if you look at his first few clips he explains derivatives and integrals.  So if you get that then you should be able to follow his nice clear "paper talk" explanations using paper and a marker.  He knows his stuff, he is a great communicator, and I encourage people to look at his clips.

He does several examples of using Ampere's Law to solve for the magnetic field for various configurations, the toroid example is just one of them.

Stand your ground all you want. I expect nothing less from anyone here. It is everyones right.

Instead of talking about the issues presented by me, well, look at your replies above.

I tell you what. If you read the itty bitty pdf and can give a reasonable dispute of its claims, of which contradict the video you posted, I would be willing to have that discussion on good terms.

I know you are trying to teach people here. But with facts like that, ones that would have Tesla laughing in his grave, someone needs to set the record straight. And on this, I stand my ground. Unless you can undeniably refute my stance on this thread subject with substantial evidence, not circumstantial. Can you do that??

I still say what was in the vid is incorrect when it comes to saying there are no fields in the doughnut holes of the core. The pdf explains it perfectly. You should really look at it.

I would like to here the guys explanation of how a secondary as I described in my previous post could be induced by a field from the primary if 'all' of the field is locked in the core.
I would really like that.

Yes Mr Eric Dollard is confused by toroidal transformer induction and says no one knows how it happens.    So I linked that PDF at EF maybe over 1 year ago.  In response to mbrowne.

Although I think it is theoretical.

I think bench tests are in order.
