How is this statement both true and false help please?

'; The north pole of a magnet points toward the earth's south pole';. Explain how this statement could be both true and false?








Any help is highly appreciated thanks!How is this statement both true and false help please?
The North pole of the earth is actually the MAGNETIC south or negative pole (white)





The Reason its called the ';north pole'; is because it is the direction the magnetic north pole of the magnet in a compass points.





The South pole of the earth is actually the direction of the MAGNETIC north or positive red pole of the magnet inside the earthHow is this statement both true and false help please?
There is a South Magnetic pole at (close to ) the Earth's North Geographic Pole.





We have allowed some confusion to creep into our naming of magnetic poles.





The ';North'; ends of magnets should be called ';North seeking poles';. Then it would make sense to label them as South poles ( since South poles are attracted towards North poles). However, we have come to call the north seeking pole of the magnet the ';north pole';, which leaves us with a north pole being attracted towards the north - towards the south magnetic pole that there must be up at the North geographic pole.





And reverse all this for the southern hemisphere.





The statement is not really true and false - it just reflects our naming confusion ( the magnets never get confused ).
because opposites attract, so the north-seeking pole points north.








qoute:


Wait a minute, why does the north end of our compass point north? Don't north and north repel each other? Well, they do, but it turns out that what we call ';North'; is actually the south pole of earth's magnet! What happened was somebody messed up a long, long time ago and named the south end of earth's magnet ';North';, and the north end of earth's magnet ';South';, and then everyone just went along with it. Wow, talk about your big mistakes!
Hehe, I really don't remember this stuff but it probably has something to do with the physical south pole and the magnetic south pole. That could be completely wrong, though.
