If you mean why planet Earth has a north and a south pole, that's the result of Earth's rotation. The rotation is around an axis; the endpoints of the axis (where this axis goes through Earth's surface) are called north pole and south pole.

What are the polarity of earth's north and south poles?
The magnetic polarity of the location we call 'Magnetic North' is a south pole, and the polarity of the location we call 'Magnetic South' is a north pole.
Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
What must be true about the polarity of a compass needle that points Northwards geographically?
'Magnetic North' is the name of a location, or a direction, and has nothing to do with the magnetic polarity of that region. In fact, its magnetic polarity is a south pole, which accounts for why it attracts the north pole of a magnet or compass (unlike poles attract).
What is polarity of a magnet?
All magnets have a north and a south pole. There is a theoretical particle called a unipole which can be either just a north or south pole. No one has ever found one.
What do you mean the south seeking pole in a magnet?
The south-seeking or, simply, the south pole of a magnet points in the direction of the location on the earth called 'Magnetic South', located in the southern hemisphere. Because 'unlike poles attract, the magnetic polarity of this location is north. By the same logic, the magnetic polarity of the location called 'Magnetic North' is south.Do NOT confuse locations ('Magnetic North' and 'Magnetic South') with magnetic polarities.
What are the polarity of earth's north and south poles?
The magnetic polarity of the location we call 'Magnetic North' is a south pole, and the polarity of the location we call 'Magnetic South' is a north pole.
How does oceanic crust record polarity?
By going from north to south
Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
What is reverse magnetic polarity?
lets say the earth was to have a magnetic polarity reversal the north pole would become the south pole, and the south pole would become the north pole. i hope that helps.
What best describes Earth's north magnetic pole?
Your expression, 'earth's north magnetic pole' is, at best, confusing. Are you referring to 'Magnetic North', which is a location and not the polarity of that location? Or are you referring to the magnetic polarity of this location, which is a south pole?If the former, then a compass indicates the direction of Magnetic North. If the latter, then earth's north magnetic pole is located at Magnetic South. In other words, a compass needle points to Magnetic North because it is attracted by its south magnetic polarity.Just to expand somewhat on this answer... 'Magnetic North' and 'Magnetic South' are so-named to differentiate their locations from 'True North' and 'True South'. In other words, 'Magnetic North' and 'Magnetic South' are locationsand not magnetic polarities. In fact, the magnetic polarity of True North is a south pole, and the magnetic polarity of True South is a north pole. I would also argue that the terms 'Magnetic North (or South) Pole' is confusing, because the location is not really a 'pole' in either the geographic or magnetic sense. By calling Magnetic North, a 'pole' causes confusion, making some students confuse their location ('Magnetic North') with their polarity ('south')!Apex answer: Wandering

What are Real world examples of polarity?
south and north pole or left and right hand or a girl and a boy
What is polarity of a magnet?
All magnets have a north and a south pole. There is a theoretical particle called a unipole which can be either just a north or south pole. No one has ever found one.
What do you mean the south seeking pole in a magnet?
The south-seeking or, simply, the south pole of a magnet points in the direction of the location on the earth called 'Magnetic South', located in the southern hemisphere. Because 'unlike poles attract, the magnetic polarity of this location is north. By the same logic, the magnetic polarity of the location called 'Magnetic North' is south.Do NOT confuse locations ('Magnetic North' and 'Magnetic South') with magnetic polarities.
What is magnetic polarity?
A magnet has a polarity, in that one end is the "north" and the other is the "south". Opposite poles attract but similar poles repell each other. You cannot make the north poles of two magnets stick together.
What is the The north magnetic pole of a compass needle is attracted to the magnetic pole of the earth.?
The needle on a compass points to the North Magnetic Pole. CommentA compass points to Magnetic North, not to the north magnetic pole. They are two different things -the first is location, the second is magnetic polarity.
What is the scientific term of polarity?
Polarity means, what kind of pole, which would either be an electrical pole with a positive charge and a negative charge, or a magnetic pole with a south pole and a north pole.
