It does look like a screwdriver, but its the transverse probe tip, here in detail with the dipole cap removed:



It does not detect the earth's field, i do see the N and S symbols flip over to N when i turn it to North, but the display reading stays at 00.0mT

I assume your gaussmeter has a transverse probe where you can apply the Fe rods.  That photo looked like something atop a screwdriver.

Yes, exactly that.  Does it allow you to "see" the earth's field?

QuoteIf Itsu wants to take this further he might be able to extend the sensitivity of his gaussmeter.  If his probe measures field normal to the probe he could place small Fe rods either side creating something that looks like a small dipole antenna but is in fact a flux concentrator.  He could then examine the field around his grating and perhaps even see the effect of heat.

Smudge, do you mean something like this:

Chet sent me a vid on how a thin downward stream of water can be slightly deflected(repelled) with a strong magnet. then they talked about how you can set a non magnetized strip of iron facing earth N and S and hit it with a hammer and it will lightly magnetize the iron. It was a woman doing the vid, and to my surprize, she was using a rubber mallet, and not really hitting it hard.  So it got me thinking that if the iron was oriented N and S earth field, that the sun could probably heat up the iron enough to allow it to magnetize.

So an experiment for that would need to follow these criteria, possibly.

lets say that while the iron is in the sun, getting all hot and bothered, test the magnetic field of the iron while hot. and if it shows a field, then apply a shadow over the iron and test again. does the removal of the light cause the iron to now not be magnetized or even lessen the field strength? IMO probably not.

Also does the irons magnetic field show orientation to the earths field?  my question would be if the light, photons, are instilling the field in the iron, what is the determining factor of this function that determines what end is N and S of that field?   

Im going to find some iron rod, or some strip and put it out in the sun, oriented N and S and leave it till dark and let it cool that way. Im thinking that if i bring it inside while hot and change the orientation, that it may not hold that field as it was initially created while it was in the heat.
so ill do both and compare. simple enough

Here is the vid chet sent me.

I have been watching this thread with some amusement.  To claim this is linked to the Casimir effect is beyond credibility.  It is obvious the guy has no understanding of (a) magnetic effects and (b) how to use a gaussmeter.  The Earth's magnetic field is stated (Wikipedia) to be between 30 and 60 mT.  To zero out that field on his gaussmeter, then place it near some Fe and claim the new reading shows a field value "created" by the Fe is just silly.  We know that a piece of Fe can concentrate the field in one close region while reducing it in another region.  Also the field vector direction changes.  His gaussmeter can be fitted with two probes, one that measures field along the probe and the other measures field at right angles.  He doesn't say which one he uses, and he doesn't change angle.  As regards the sunlight effect, as someone who has used metal tools that have been exposed to bright sunlight I know that the incident and reflected sunlight near his mirror will significantly heat the Fe and that will alter its magnetic characteristics. So IMO his results are not showing something significant.

If Itsu wants to take this further he might be able to extend the sensitivity of his gaussmeter.  If his probe measures field normal to the probe he could place small Fe rods either side creating something that looks like a small dipole antenna but is in fact a flux concentrator.  He could then examine the field around his grating and perhaps even see the effect of heat.

I could not resist as i had both the 1cm by 1cm store bought grating and a gause meter lying around.

Toke me little time to set it up, and the sun was there the next day, so here the result: https://youtu.be/lZM_SRMQ3I0
Outdoors result starts at 4:15 in the video.

Regards Itsu

Let me know what you find. Their info is public.

It's very good in Hermes. qwen 3.8 obliterated if you have the space is a very good non censored model. But yeah ANthropic sheesh!

Quote from: JimBoot on 2026.10.06, 23:56:14Thanks Chet. https://www.vals.ai/blogs/room-temperature-magnetic-semiconductors Opus 5.5 use a bunch of agents on materials high temp semiconductor research. Anyone made KV[Cr(CN)₆]  before? Edit: Bottom line: the synthesis appears to be a wet-chemistry problem, not a cleanroom or giant-furnace problem. But air-sensitive vanadium chemistry and cyanide-containing materials make the lab and operator more important than the shopping list.

I find Opus 5.5 unusable.
Any low-level technical question to it ends up with this shit:

Quote from: Opus 5.5My reply to this was stopped partway by an automated safety classifier, so nothing I wrote about this subject reached you. It wasn't a tool or connection error, and I can't tell you which part triggered it. Because of that, I'm not going to retry that analysis and I shouldn't produce it again in other words.

What I can still help you with the high-level overview.

If you think the classifier got this wrong, the thumbs-down button on this message sends that feedback to Anthropic.
