The red tip IS south because it aligns itself with the field, not attract the poles.
Thread done.
You apparently didn't watch the video on page 2. They put a bar magnet on a table and line up compasses around it. Opposite poles attract and you can see what happens in the video. Your explanation doesn't resolve the discrepancy, but you're right the compasses align themselves with the field, but they do so in the opposite way most people expect as she explains in the video.

Here's the link to where the video was posted:

First, I could be wrong by asuming that "aligning " translates to what I wrote but it seems that´s not the definition.
Because when you think of aligning with the magnetic field, you come to that conclusion. Since aligning fields mean just that: NNSS. Now whats right? Does a compas needle align with the field or is the tip attracted? That´s the real question.

I watched the video but (I thought I got a good preview in the box, before).

She says those compasses are south seeking. Somehow confusing because if its a north seeking compass(so are the mayority), the needle of north will of course point to north and thus south to south so you can call it both ways. The real use for north seeking is when you hang the magnet it you normally define the north thus you call the pole "north seeking pole", not "north pole".

So is it aligning with the field (meaning the direction of the field) or is aligning = attracting opposite poles??

In that statement is the gist of this thread. Most people think the needle of the compass is seeking north, but it's only seeking geographic north. When she says it's south seeking, she's referring to magnetism, not geography, because the Earth's magnetic field isn't relevant in her experiment, as the field of the magnet she is using is many times stronger at such a close distance. So the red tips of the compasses all point to the magnet's south pole, but if you move the compass away from that bar magnet, the red tip will point roughly to the Earth's geographic North, which is actually a magnetic south pole, which we confusingly call the magnetic north pole. Confused yet?


So is it aligning with the field (meaning the direction of the field) or is aligning = attracting oposite poles??
The compass aligning to the magnetic field and opposite poles attract is pretty much the same thing, in 2 dimensions which is all the compass gives us. If you had a three dimensional compass you'd see that depending on where you were on Earth, the Earth's magnetic field isn't always parallel with the surface, as sometimes it comes out of the ground at an angle, especially at higher latitudes. In the past such a device that would tell you the true alignment of the magnetic field was called a dip circle.

Dip circles (also dip needles) are used to measure the angle between the horizon and the Earth's magnetic field (the dip angle). They were used in surveying, mining and prospecting as well as for the demonstration and study of magnetism.

I agree with you except the following:

No it´s not the same. The field flows from geo South(magNorth) to geo North(magSouth)
So if we talk about aligning WITH the field the magNorthCompassNeedle would point to magNorth. (NNSS)
The opposite of what is the reallity it seems so technically it does not align with the field but rather the tips are attracted SNSN

ah nevermind goddamned it´s to late for such brain#s you are right all the way. I got way much to confused with that aligning #.
Not my day. You win
