This video demonstrates how to us a magnetic compass to determine the direction of the local magnetic field: the north end of the compass needle points in the direction of the field. Also demonstrated is the field of a bar magnet, visualized using one or more compass needles.
This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

Planetary "north magnetic pole" is actually the southern pole field of the planet. Hence the red needle portion of a compass is polarized north.

Okay so my compass flips 180• in a certain area top and bottom of my home. Right at the place I have been naturally drawn to stand at for three yrs. The radical 180• flip starts outside… in a diagonal line from kitchen door diagonal 20•NNW… In the zone it then flips 180• eastwards then back in to the 20•nnw? This pattern continues south to north in a diagonal cross of my house… Can u help me understand… cause I’m thinking maybe I do have a whopping ley line under the hse. Does that sound reasonable. And yes I have check the compass and tried it on the phone with the same results….!! Is this a signature of a compass picking up a ley line… Would you be able to enlighten me on this. Cause I’m quite confused about it? As this demo shows what happens to my compass. I’m very curious to know more about the why

The Earth has a whatever magnetic pole on a side which we, humans, decided to draw on top of our maps; and it has a whatever another magnetic pole on the other side which we agreed to draw on the bottom of our maps. So now the planet has the 'upper' and the 'lower' magnetic poles. Then we invented a compass with a straight needle. It has its own whatever magnetic side 1 and a whatever magnetic side 2. The sticking-to-the-upper-pole end and the sticking-to-the-lower-pole end. The first is marked red, the other one is unmarked or marked blue. We, earthlings, agreed that the planet's pole that attracts red end of compass needle is North. The planet's pole that attracts the unmarked/blue end of compass needle is South. I always thought that the Earth is a giant permanent magnet and a compass' needle is a small permanent magnet. In order to point North with its red end the needle has to have South pole there-cause two different poles attract. Thus, if the planet's 'upper' pole is North, the needle's "northern" red end must have south polarity. If the planet's 'lower' pole is South, the needle's "southern" blue end must have northern polarity. If we place a permanent magnet (I assume it must act as a smaller equivalent of the planet) near a compass and the compass attracts its "southern" blue end of the needle to the red northern end of the magnet-it means that either all the magnets we have are marked wrong (blue and red must swap places), or we actually have southern magnetic pole on the planet's North.

Comment to my own comment after some research: Yes, our planet's North is a magnetic South and its South is a magnetic North. Oh cringe. Thus we name the Earth's magnetic polarities not by their features, but rather by the name of respective end of a compass needle.

Which means that there is no central South Pole (negative) on earth because the south end (positive) would be attracted to it the closer to the "south" you were. The south pole of earth is it's perimeter, the North pole is the centre.

What makes you think the field flows out of the north pole and around and into the south pole? The field flows north to south inside the magnet, and then continues out of the south pole and around and into the north pole. Why do you think otherwise? There is nothing in your demonstration that indicates direction of flow.

Magnetic field lines moved from n to s outside the magnet and s to n Inside the magnet and about these field lines you can do the experiment by yourself just keep a bar magnet on a paper and some iron piece around it tap the paper gently you will see the shapes of that iron piece which will indicate the magnetic field lines and thats how you prove it sir
