    Cutting Magnet Wall
Click For Summary

Discussion Overview

The discussion centers around the proper method for cutting a FeBa magnet to ensure that a Bloch wall runs across its entire length. Participants explore the implications of cutting the magnet with respect to its dimensions and the orientation of the magnetic poles.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks guidance on how to cut the magnet to achieve a Bloch wall across its length, specifying the dimensions of the magnet.
  • Another participant expresses confusion about the concept of a Bloch wall and requests a visual representation to clarify the discussion.
  • A participant provides a link to an image of magnet poles but does not clarify the Bloch wall concept, leading to further confusion.
  • One participant suggests looking up Bloch walls, describing them as the boundaries between magnetic domains.
  • Another participant questions the continuity of the Bloch wall, referencing their past experiments that indicated magnetic domains can be disorganized.

Areas of Agreement / Disagreement

Participants express differing levels of understanding regarding the Bloch wall and its properties, with some uncertainty about its continuity and the behavior of magnetic domains. The discussion remains unresolved regarding the best method for cutting the magnet.

Contextual Notes

There are missing assumptions about the properties of the magnet and the specific conditions under which the Bloch wall is considered continuous. The discussion also reflects varying levels of familiarity with the concepts involved.

Hello,
could someone explain to me, how I should cut a FeBa magnet, if it has one pole facing upward and the other downward so that the bloch wall would be across the entire length of the magnet. The dimensions of the magnet at hand are 152 x 102 x 52 mm. The bloch wall runs across the entire length of the sides (152 length, 52 height) and the side with a length of 102 mm and height of 52 mm, just to make it as clear as possible. Just don`t want to cut them the wrong way, that`s all.
Thanks to anyone in advance.

I don't understand this ?please show a photo of what you are talking about
 
@davenn, have you tried looking up Bloch walls? It's the rather common term for the walls between magnetic domains.

@Sveral, are you entirely certain that the Bloch wall is that continuous? From my experiments in my EE studies back in the day, magnetic domains were pretty haphazard and all over the place.

About the domains I agree, yes, they disorientated under normal conditions. But this was about the bloch wall and cutting magnets, but I will get through it, don`t worry.
