Magnet Myths and Misconceptions

[synchro1]

How do you think that anything in that cited quotation supports the idea of a "magnetic equator" in a permanent or electromagnet?

@MarkE,

Why not ask how it effects the price of camel milk in Timbuktu. Just another "Screwball"! Find how it does that on your own!

I think that we can interpret that as an admission that you were wrong about the Bloch wall being at the center of a bar magnet.  It looks like you have been doing some serious online research about Bloch walls and did not find any references from legitimate sources to back up the claim that a Bloch wall exists at the center of a bar magnet.

Beyond that, all that you really have to do is put your brain in gear and THINK and understand to agree with the fact that there is no Bloch wall at the center of a bar magnet.  The entire idea is nonsensical.

@TinselKoala, @MarkE, @MileHigh - I repeat what I said - Modern Science in different disciplines, today, don't agree with your Myths and Misconceptions on Magnets!

You are wrong about Magnets! Period.

No amount of Verbal Debate will prove other wise. East and West on a Compass represent the Equator just in-case previous diagrams have you confused.

I suggest you take some Physics 101 Classes or Astro-Physics 101!!!

Your Science is out-dated and incorrect!

Stop PREACHING Bad Science! Your opinions are yours! Stop trying to inject your opinions into people. Opinions are NOT SCIENCE!!!

Kindly allow me to rephrase:  Please materially connect the contents of the citation to what you are attempting to argue.

    I see you are still doing what you do best, Synchro: Misrepresenting the work of others, that you do not understand.

    See if you can find such a photomicrograph that shows a "Bloch Wall" running along the center of a permanent magnet. Then try to explain why, when you cut a PM in half along the center, you get NOT two "monopole" magnets but rather two ordinary bipolar magnets, each with what you wrongly call a "Bloch wall" in their centers. It's a funny kind of "wall" that splits and moves just because you have cut along where you thought it was.

    As MH told you earlier, Bloch walls are actually just what your photomicrographs show: Domain boundaries. And he has also told you the truth: In Permanent Magnets, most of the domains are oriented in the _same direction_ , not randomly like the images you have presented. Bloch walls exist between all the tiny magnetic domains that are randomly oriented, not along the "equator" of permanent magnets.


@TinselKoala,


Misrepresenting the work of others, that you do not understand.

"Ibid"  from an eccentric "Trash Harvester"!

Let's see what you make of it Einstien!

Abstract:

"Domain-wall structure in thin films with perpendicular anisotropy: Magnetic force microscopy and polarized neutron reflectometry study".

"Ferromagnetic domain patterns and three-dimensional domain-wall configurations in thin CoCrPt films with perpendicular magnetic anisotropy were studied in detail by combining magnetic force microscopy and polarized neutron reflectometry with micromagnetic simulations. With the first method, lateral dimension of domains with alternative magnetization directions normal to the surface and separated by domain walls in 20-nm-thick CoCrPt films were determined in good agreement with micromagnetic simulations. Quantitative analysis of data on reflectometry shows that domain walls consist of a Bloch wall in the center of the thin film, which is gradually transformed into a pair of Néel caps at the surfaces. The width and in-depth thickness of the Bloch wall element, transition region, and Néel caps are found consistent with micromagnetic calculations. A complex structure of domain walls serves to compromise a competition between exchange interactions, keeping spins parallel, magnetic anisotropy orienting magnetization normal to the surface, and demagnetizing fields, promoting in-plane magnetization. It is shown that the result of such competition strongly depends on the film thickness, and in the thinner CoCrPt film (10 nm thick), simple Bloch walls separate domains. Their lateral dimensions estimated from neutron scattering experiments agree with micromagnetic simulations".

@MileHigh,

"This whole notion of a Bloch wall at the center of a magnet is a ridiculous nonsensical farce and is just another kind of "delayed Lenz effect" sickness".

Here you compound your bullshit. Why not include your "Mythbusted" Tesla series bifilar while you're at it?
