Magnet Myths and Misconceptions

[MarkE]

Bill, I don't know of a specific experiment, but it is likely that something like that has been done.  Don't forget that NASA also uses cargo planes they put into free fall to get zero G without going into orbit.

Do you believe that he has established any evidence for a Bloch wall at the
center of a bar magnet?

No I do not believe it is a Bloch wall and I have reservations about his corialis force theory however I also believe he has shown more than enough data to suggest that something is happening to the external magnetic field near the magnet center.

Do you believe that he has established any evidence for the idea that magnetic
field contours around a dipole magnet form a figure eight, extending not from
pole to pole, but extending from each pole to the center of teh dipole
magnet?

Yes I would agree he has posted more than enough evidence to suggest something is happening to the external magnetic field near the magnet center. I posted a picture and he also posted many other pictures in direct contradiction to the conventional view.

If you believe in this curling near the center of the magnet, then why does test
after test show that the field is in fact its most parallel to the dipole axis
at the center rather than curling there?

You have shown pictures of iron filings and of a compass around a magnet however this in no way changes the fact that his evidence does not agree with yours. You are trying to argue it is an apple by showing an apple despite the fact his orange is sitting right next to you, ignoring it does not make it go away. So why are all the pictures of different experiments showing a curvature?--- That is the question we want an answer to. Not lectures, not the past or equations --- why are all these pictures showing as a fact that the external magnetic field is not parallel to the dipole axis?. A simple question which nobody has answered and in fact they have avoided it completely.

EMJUNKIE has posted so many messages that are completely over the top that it is
looking more and more that he is just putting on an act.

His posts or messages do not change the evidence he has presented it speaks for itself .

@Mark No I do not believe it is a Bloch wall and I have reservations about his corialis force theory however I also believe he has shown more than enough data to suggest that something is happening to the external magnetic field near the magnet center.

Kindly point to the evidence you find the most compelling.

Again please point to the evidence that you find the most compelling.

You have shown pictures of iron filings and of a compass around a magnet however this in no way changes the fact that his evidence does not agree with yours.

Do you contest that a compass needle aligns closely to an external magnetic field, even one as weak as the earth's?  If you do not contest that a compass so aligns, and if you believe his contention that the field curls near the center of the dipole then how do you account for the fact that a compass in fact does not turn towards the magnet at its center even when the magnet is aligned E-W to the earth's magnetic field, thus providing the earth's magnetic field over and above the curl claimed?  How do you account for the fact that as EMJUNKIE himself acknowledges that a bar magnet passed through a coil at constant velocity monotonically crosses through zero voltage as its center approaches and crosses through the coil, when the double curl he hypothesizes would dictate a double voltage inflection around the midpoint?

You are trying to argue it is an apple by showing an apple despite the fact his orange is sitting right next to you, ignoring it does not make it go away. So why are all the pictures of different experiments showing a curvature?--- That is the question we want an answer to. Not lectures, not the past or equations --- why are all these pictures showing as a fact that the external magnetic field is not parallel to the dipole axis?. A simple question which nobody has answered and in fact they have avoided it completely.

Where has EMJUNKIE posted even a single picture that is accompanied by a description or link  to the experiment set-up, that shows any evidence of his claims?

His posts or messages do not change the evidence he has presented it speaks for itself .

Yes, it speaks very badly.

I found posts #344,346, 418 and my picture at #332 seem to be in favor of something happening near region of the magnet center.
I understand your perspective and I agree with most of it however I also think one has to keep an open mind. Some people seem to think this is a for or against scenario however I'm not completely for or against anything one hundred percent. The pictures show something which seems out of the ordinary from my perspective and I have not heard an explanation which I feel describes what I have seen completely.
What I do not agree with is people calling other people stupid or ignorant simply because they disagree on a topic. Is there something there, does it actually curl? --- who knows however I thought that was why we are all here isn't it?. I found the picture #332 I posted the most compelling and while the field may come parallel near the center the curl would seem to be undeniable and unexpected.

Where has EMJUNKIE posted even a single picture that is accompanied by a
description or link  to the experiment set-up, that shows any evidence of his
claims?

Most of these pictures are all over the net and I have seen most of them before at one site or another. In any case to really understand something it should be a hands on experiment which we can do ourselves and I will have to think on an experiment we could do to prove this for ourselves one way or another. We know the iron filings experiment is against curl however that does not mean all experiments are in my opinion. It would seem to me the smaller the particles the greater the curl near the center which may be a good place to start.

I just had a thought, generally I go through a learning process where I look at the the problem objectively then reverse it then try to visualize it from multiple perspectives.
Does the field curl?, if it did then why?, how could we make it curl inward?, what are the consequences?.
As such it may or may not curl in reality however just going through the logical steps will generally produce some insight and we may even learn something new however if we just deny it then we can be pretty sure were not going to learn anything. That's my theory... I'm here to learn something new.
