bohm2, regarding what you said earlier about Bell's comments on free will, will these experiments (1, http://discovermagazine.com/2010/apr/01-back-from-the-future#.URdziWc4D0c) on future decisions affecting past outcomes solidify the possibility that:

Thanks everyone for your replies. Fredrik: The book page you link to in your earlier post still mentions "measurements" and implies that uncertainty is only relevant to human observation. However, in your post you say that "that actually appears in QM has nothing to do with "nudges" or...

Hi, I have taken an introductory undergraduate QM course, solving for different boundary conditions like particle in a box, but the physical interpretations of some of the tenets was not well explained. I was surprised to find this paragraph on Wikipedia: "Published by Werner Heisenberg in...

If a slow elementary reaction between two colliding species takes 2 s, and a fast step afterwards takes 1 s the total time is 3 s. Since the time for the overall reaction's completion is increased by the fast step, why is it ignored in determining the rate law? Thanks, P.S. This is not a...

Ok I missed the last sentence of your last post, but I understand now. Thanks.

I see what you mean from those hysteresis plots, it seems as if there are "two types of slopes", the one going up and then a less steep one when you are fighting the remenance. So I guess this means absolute permeability is actually a range between these values.

Ah, thanks for that. But now I am at a loss as to how I can determine the permeability : ( because I was relying on the magnetization being an indicator of high permeability.

Thanks for your reply.

Heh, I'll consider this thread "solved". But our actual discussion in the other thread will hopefully be moved to a general forum since I pmed a moderator.

OK, thanks for sharing this info with me. But it seems that the magnetic susceptibility will have to be determined experimentally out of practicality, or else my head will explode going from relationship to relationship :P But in order to do this, I would have to test with frequency close to...

I will ask a moderator about moving it.

If a material has a higher permeability (electromagnetism) than another when in the presence of a fixed H field, would it generally also have a higher permeability when in the presence of a changing H field?

What if the ferrite is a thin film? It's going to be used as a core in a radio application, where the time varying H field comes in.

Thank you very much for your response. The ferrite I'm going to work with will be a few microns thick, which I think is still far bigger than subdomain level so some hysteresis will be present. I have read that the loop for this ferrite isn't very thick (soft magnet), I'm not sure if that...

Homework Statement I am doing a project for which I am learning some aspects of electromagnetism by myself, so you can imagine how lost I am. Well, not completely: I was searching for a ferrite with high permeability as a core material. I learned how the octahedral and tetrahedral sites and the...
