What point on earth is the only place from which all directions face south?
The North Pole - because whatever direction you walk in away from it you will always be heading south. The North Magnetic Pole that is. Geographic North Pole is the correct answer. The magnetic pole is actually not in alignment with the geographic one.
Needle on compass always points to what pole?
The magnetic poles of a compass needle are named after the directions in which they point. 'Magnetic North' and 'Magnetic South' are LOCATIONS (used to distinguish them from 'True North' and 'Magnetic North'), and do NOT describe their magnetic polarities. As 'unlike poles attract', the north pole of the compass needle points towards Magnetic North, whose polarity must, therefore, be south. By extension, the polarity of Magnetic South is north.
Where is the compass arrow always set?
It automatically points to magnetic north unless it is influenced by some other magnetic source.
Does the magnetic compass always point in a northern direction when placed on the earth?
No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!
Why does a compass always point north when picked up?
Because of earth's magnetic pull
What point on earth is the only place from which all directions face south?
The North Pole - because whatever direction you walk in away from it you will always be heading south. The North Magnetic Pole that is. Geographic North Pole is the correct answer. The magnetic pole is actually not in alignment with the geographic one.
Are the magnetic in the north pole and the geographic north pole always the same distance?
No, the magnetic pole is always on the move, which is why the magnetic variation is often printed on maps.
What instument always shows magnetic north?
A compass is the instrument that always shows magnetic North. A compass is used to show which way you are traveling.
Why does south pole of the compass always point to the north while north pole always points to the south?
Like magnetic poles repel, unlike magnetic poles attract. So the magnetic south and magnetic north of two bar magnets will attract. Therefore, though the compass needle points towards the magnetic north, it is actually the magnetic south pole of the compass needle that is pointing towards the magnetic north.
How do birds know where north and south are?
It has been postulated that a special part of migratory birds' brains contain a magnetic material which keeps track of the bird's alignment with the magnetic field of the Earth.
The neeedle on a compass always points on what pole?
magnetic North
Where are Magnetic poles are strongest?
It is north of the equator by Greenland, why do you think compasses always point north? It's because Greenland has a lot of magnetic occurences in that area and since it has so much magnetic occurence, the compass will always be pointing there
Why does a bar magnet become weaker after you drop it on the floor?
It disrupts the alignment of the North and South poles.
What are types of evidence that the sea floor is expanding?
Rocks have a north and south pole. The sea floor was discovered to have different magnetic poles on cracks in the ocean floor.

What happen if the magnetic north is not the same as true north?
Nothing. The truth is, they have always been different.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
