Magnetic weapons

[Rivkin]

A fantastic picture. I see that most of the blade is not magnetized at all, but there 4-7 macrodomains, which are magnetized. I would say that there definitely has to be some kind of a structural nonuniformety at these points. What surprises me that these domains are quite big, moreover rather than forming let's say a vortex like structure they are actually very well separated.

For now I would say that there are 4 areas that either cooled much slower than the rest of the blade, or somehow else vastly differ from the rest of the blade.

I'm not surprised to see N/S/N configuration: the interaction in between of these areas is obviously dipole-based, and knowing the fact that is magnetized perpendicular to the line that connects these (I don't really want to confuse people by saing "domains") areas, the most benefitial configuration would indeed be the one with the opposite magnetizations.

I will try to get some other opinions on this image - great stuff, thank you.

Thank you very much for the work Gene, it paid off, the pictures are fantastic. Please show us a picture of the blade and a close up of the blade. Thank you for making the experiment.

Rivkin, you obvious know a lot more about this than most of us, which is very good. The trend started as an amateur discussion, but has moved on far beyond that.
You write: ‘For now I would say that there are 4 areas that either cooled much slower than the rest of the blade, or somehow else vastly differ from the rest of the blade.’
What do you mean by writing ‘cooled much slower’ – how much slower would it need to be to give this effect?
When you write ‘or somehow else vastly differ from the rest of the blade’ what do you mean by this – differ in what way?
Could the blade have been made in this way by polishing it with a lodestone?

This is a picture of the dagger.
RIVKIN Thanks for your comments on the picture.
I would like to tell all that would try and duplicate this, is this. Be ready for a lot of frustration! as I tried this well over a 50 times over a two weeks time period taking hours and hours of time. I gleefully jumped into this project and just dumped the Iron Powder over the covered blade, sorry it did not work at all for me. To make a long story Short, I had to make a box (patten applied for! )that would hold the dagger level and keep all wind currents away from the Iron powder (sneezing will do "wonders" to the effect, don't ask ) I had to just about place each Iron particle by hand on the paper, as the Iron powder would not form a pattern if to much was used in one place and it had to be even over all the blade. I also think that by leaving it undisturbed, with the Iron powder in place, for two days did allow the Iron powder to take a "set", that's my thinking anyway. It would be nice also if your Iron powder was not rusty as mine was, it sure is messy, and will cause you to sneeze (I said do not ask!). The Zinc coated Iron filings just did not work well for me as it was just to course however it did not cause a mess or make me sneeze.

Gene, could you not have polished the iron powder before you started the experiment? It would have made it a bit less messy . If yje iron powder is very fine, could you not have used a pepperboxto distribute the powder?
From which part of the blade is the experiment?
Thank you for taking your time .

Many blades become magnetized by the stroking of the grinding and sharpening processes; Many of my everyday knives and chisels display this affect, but the pole changing seems weird, and though I've never tested, the magnetization of knives from sharpening seems to be only along the edge and/or tip.
Hot working magnetic steel will demagnetize it, but not all of us knew that. Allow me to propose that the original costumers didn't know it either; perhaps this was a gimmick to "demonstrate" a blade being from a famous magnetic ore deposite (or of course, to suggest other magical/spiritual powers; look how modern paranormalists use their thermometers, manetometers, electrometers, etc.).

If you look close at the larger of the two pictures (the one I used Iron powder on) on the left side you can just make out the hilt of the dagger so the orientation, is sharp side of the blade is down and T back side is up and closest to the paper and Iron powder. JENS where were you when I need you? Clean/polish the rusty powder indeed what should I have used Simichrome, or WD-40?

I also must tell you all that I made a big mistake in doing all this . For when I moved the dagger, from taking the last picture, it fell out of the box I used to shield it, the dagger fell about five feet and hit on my concrete floor, hitting the heavy hilted end with enough force to smash one of the gemstones in the hilt end, the stone was a Peridot. I will have it replaced next week (I hope) but I am now afraid to even check to see if the pole reversing was effected in anyway, as some of the forum folks here have stated that blows will effect the magnetic properties of steel, but will do so just as soon as I get over all this. I'll keep you posted.

Gene, why do you ask? When you were supposed to polish the iron powder, I was out walking the dogs - of course .
I am sorry to hear about the dagger, and hope that nothing has happend to it. Should something have happen, try to ask Ann, I am sure that she will be able to help.
