I have a steel straight edge. It is stored near (and not that near) 3 small rare earth magnets (in a sanding jig). Today I was looking again at concavity in straight razor spines. I noticed this: several of my razors do not respond the the weak magnetism of the straight edge, and some will pull to the straight edge when that edge is close to the spine.
I'm putting the question here as it must have something to do with the composition of the steel.
from the interwebs,
" the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic.
One of the razors which does not respond to the weak magnet is a 19th century Greaves. Another is a mid 20th century Fon Golden Star.
I don't think any of my razors are not attracted to magnets...I will check tonight to see but I have a magnet holder and I have never had a problem with a blade sticking.
Ernie, the straight edge is a weak magnet, a magnet by proximity to a a real magnet...if I were to put any of my blades on the jig with the rare earth magnets they would glue down quick. This is the weird thing, as the weak magnet is pulling in some razors and not others.Quote:

Ok I think I see now what you are saying- it's one of those "magnetic" blades that were a fad for a little while like my Carbo Magnetic?Quote:

I was thinking the same as wirm, esp if you use magnets to hold the razors in place when working on them. I suppose there is also a possibility of the polarities of the magnetic fields making a difference. Push or repel force might require more force to generate a visible response than pull or attract forces. I realize that in an otherwise neutral experiment this might not be the case but taking into account the pivot and shape of the razor it may.
"A weak magnet tells you...." that you have to much time on your hands to be pondering such questions?:shrug:

Tried rotating the non attracted blades 180º ? I'm thinking reverse the polarity ie like poles repel but a weak field may give the illusion of not attracting.
Here is what happened. Only one of the razors in this 'test' were on the jig with the rare earth magnets, so I dismissed that as a factor. But after playing magnet for awhile, and having a few voices of reason, I remembered that I once had the razor jig in a top drawer of a chest of drawers and on the top was, right as rain, my razors all lined up in the corpse pose,
resting. So back to my look at concavity in razor spines without the added sky is falling factor.
Gee, 'Frendo"! That were not very nice! :p He was just funnin'! :shrug:Quote:

I'm thinking Darl had a pile driven, and an H beam put on that. Then he would have welded on a piece of 1' plate steel and mounted the demag to it.
Sounds like something he would do! :rofl2:Quote:

Personally, I find magnetic iron quite attractive..
;)
yea, I said that..

During my Navy days ships had to undergo periodic demagnetizing (degaussing)of the entire hull.Quote:

I did a giveaway a while back of a shortie. Guy said it shaved great, but as he pulled it out of the pile, all the others followed! Yes, a magnetic jig was involved! :rofl2:
That was before I got 'demagnetized'!
I have a demagnetizer for watches which will work for straights as well.
Like Tom says, "Learning every day;)"
Steve, I had to look up what exactly demagnetizing a watch meant, beyond the literal meaning. Pretty easy to grasp. In the process of reading about it, I read that there are some watches that are resistant to magnetic forces like this:

Do you think it would look gaudy on me? I don't see it that way really. So I'm thinking right after I scrape up enough coin to get a 3-pac of underwear I might acquire one :)
I understand how a fella would, given an appropriate amount of discretionary income, collect watches. They can truly be things of wonder. I'll bet there are even forums devoted to the minutiae of horology where those characters go on and on.....and on.
Indeed, but Ni by itself ferromagnetic, which is funny- get a piece of pure Ni...problem solved. Ni amidst Cr and Fe though- you have a bunch of different electron spin configurations that are not in sync. They are different sizes and therefore it's the distance from atom to atom that puts their orbitals out of sync. The electron spin must be in sync for magnetism to work. so I ask: did you try unplugging the razor and then plugging it back in again? :thinking:Quote:
