Like.
t too thnk the inclusion of remanance in the discusson is likely not fruitfuil. I do think it important, however, to remember that... -
Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.I do think if the nail is a permanent magnet, that the tip will be of one polarity and the head of the other polarity. That would make...

Iron with a low carbon content, is a "soft" magnetic material. The steel used to make nails has high carbon content, which makes it a...

Charles Link reacted to magnetics's post in the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary with Like.
The nail is just a typical steel (ferrous) nail from a shop. Being a soft magnetic material, there would be induced magnetism while...

Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.I presume you are referring to any permanent magnetism, if there is any, appears to be minimal, but why not check for it, like...

Just because you have a reasonable sounding explanation does not make it correct. Confounding factors should be tested for and...

Charles Link reacted to magnetics's post in the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary with Like.
I was experimenting with multipolar permanent magnets (concentric alternating-polarity) and a nail and noticed something that initially...

Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.From the response of the nail it is likely it is not permanently magnetized, if that is what you are referring to. It is responding how...

That makes sense. Thanks for that. The image from OP there are three alternating poles, with the two ring magnets and one central disc...

Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.It is starting to make a little more sense, now that I have a clearer picture of it. I think the flat head is extensive enough that it...

It looks like they are called "Spiral Shank Nails", and the grooves afford superior holding power for the nails: I don't think the...

Charles Link reacted to magnetics's post in the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary with Like.
It could have been explained better, I agree. The magnets in the photo are static magnets and the interpole boundary is the neutral line...

Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.You've got a very odd looking nail. I thought the head of the nail was the magnet. That is the head of the nail as I know it. You...

Charles Link replied to the thread Graduate Practical demo - Ferromagnetic attraction at interpole boundary.The pictures were unclear and the OP's explanations were lacking. I think that larger surface with 3 rings is the sensor, but I don't...
