Magnet Myths and Misconceptions

Because there is No Magnetic Field at the Bloch Wall the Support a Convex?

As the domains within the center of the magnet are still aligned,i really cant see how it is a bloch wall. But it really dose seem to be a null zone. Anyway,in a week or two,we will know for sure what the field shape is.

Tinman,

as i see it, your both pictures (first EX1) are confirming what MarkE is trying to tell you guys all along.

You guys are looking at the same famous picture of an old woman or a beautiful lady depending on how you look at it.

 
Open your mind, change your view, only then you will see

Yes,because it is like i said,the field changes from X to Y,so my statement is correct when i say that the field left of the dipole center is different to that of the right of the dipole center. So the field is not a uniform field,infact the field is opposite. And the field at the center that is suppose to be of the highest density produces no power at all when swipped across an inductor. This field that is suppose to be there is a nothing field-it dosnt attract feromagnetic material,and it dosnt produce any power when passed across an inductor. Then there is the big iron filings rubbish,when all of a sudden iron filings now stick to this field that has no attraction to feromagnetic material,and produces no flux through the core of an inductor-->but is the largest flux field around a magnet

You see poynt-it just makes no sense. How can one of you top notch guys say-Quote:When you swipe an inductor past the north end of a magnet, you obtain a strong pulse of polarity x. When you swipe the inductor past the south end of the same magnet, you obtain a pulse of roughly the same magnitude, but polarity y (the opposite to x),
And then we get from another top notch guy saying Quote: This is wrong.  The field is fundamentally the same.  The center of the dipole will have the highest strength field, but the direction of the field does not change.

So we got one bloke saying we have an X and Y field,and another saying this is wrong,the field is the same,the direction dose not change.
Direction of what?--is this another man made muddle up?,and how can it not change if each end of the magnet produces the opposite sine wave output when the magnet approaches and leaves the core of an inductor?.

As far as the iron filings go,they do nothing more than build a path for the magnetic flux to follow. And the strange thing about this is,you can shape those iron filings how ever you want them on the paper on top of the magnet,and they will stay there--aint that a hoot.

Brad, remember my post explaining why you had the most induction when your pancake coil was in the middle? If not, perhaps review it.

The magnetic field of the magnet is not the strongest at the middle, in fact it is the same all along from end to end. But at the center, there is a maximum NET flux that can be intercepted by your coil, provided the coil encircles the magnet as you have shown.

What kind of magnetic field(flux) dose not induce a steel core when it passes by it?-none that i know of. This is a field that cant induce a feromagnetic core in an inductor to produce power,it is a field that dosnt attract any feromagnetic material. It is a Claytons field-the field you having when your not having one.
We see all these pictures(see below) of these wonderful field line's(which we know dont exist)
We see north and south writen all over them,and also what we learnt in school-but dont exist
And all these arrows that show us the direction of-->we dont know what.

All the test i have carried out can find no evidence of this field
The pic of the ferrofluid shows no evidence of this field-even the underside.
And the only evidence that has been shown that this field exist(other than hearsay)is iron filings sticking together due to them giving the flux a path to follow.

!st of many experiments carried out in the past year.
The picture tells the story,so no need for a long post.
