Poles Reversing

[CLaNZeR]

As said before I do not go to technical with magnets, I tend to build and try and use my little clear box full of iron filings to see the Flux gate around the different magnet configurations I set up.

But tonight I was playing with placing two magnets South against South that were kept in line using nylon thread.
I then introduced a big magnet to watch the spring effect happen and examine what effect it would have at different angles.

I was suprised to see the pole had changed in the middle of the magnet.
Is this normal?

It is easier if I attach a diagram.

I think it's similar effect as the movement of a magnetized soft iron across the "neutral line"

Scroll down in that link to get the pole flipping effect. Fascinating stuff
It makes sence too. As at "far" distances it is oppositie but on contact it assumes the polarity of the contact pole.
So, somehwere between contact -zero distance- and "far" there is a point of pole flipping.

Thanks for the link Mike, will have a good read of that.

I forgot to say the magnet that I was playing with has remained reversed in the middle.

A very interesting find...
Can you give me more exact info about the components so I can attempt to replicate it.
I will buy the parts this weekend. It is quite curious that the poles have remained flipped.
Please explain with detail... Examples: were the magnets verticaly or horizontaly stacked?
Were the magnets ceramic or NeFeB? where did you obtain them? Any other details would
be great. I'm quite interested in seeing this effect first hand.

Thanks for the interesting post!

If you remove the left most (2 hole bar) magnet do the poles reset in the center?
