Electric currents circulate in the interior of the Earth, and these create an magnetic field, with a north pole and a south pole. But not necessarily aligned with the geographic (spin) poles.
If a rock which contains ferric particles is cooling, then those ferric domains will assume the direction of the Earth's magnetic field at the time the parent rock passed through that minerals Curie point. It will contain some 'fossil' magnetism.

How would you use the Earth's magnetic field to tell you where on Earth you are?
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
Earth's magnetic field is believed to be generated from what region?
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Does the earth's magnetic field give information on the earth's interior composition?
The earth has electric currents in its structure, that create magnetic fields.
What is the process by which Earth's magnetic poles change places?
Magnetic reversal
When does the north pole become the south pole and the south pole become the north pole?
Answer The answer is no, of course not! It is the magnetic polarity of the earth that is being flipped, not the locations of Magnetic North and Magnetic South. Remember, 'Magnetic North' and 'Magnetic South' are locations, not magnetic poles. So even if their magnetic polarities flip, the names of the locations won't ever change! All that would happen is that the magnetic field would reverse, and your compass would point to Magnetic South instead of Magnetic North.Think of it this way, if the magnetic polarity of the earth flips, you wouldn't swap the names 'Arctic' and 'Antarctic'! So, why would you swap the names 'Magnetic North' and 'Magnetic South'!!!!!
Earths magnetic poles reverse approximately every years?
The process of the reversal of the Earth's magnetic poles is called a magnetic flip. This occurs every 4 or 5 times per million years.
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
What is resion of Earth magnetic field?
The Earth's magnetic field is the result of electrical currents flowing in the earth.
What are load stones?
lodestone is a form of magnetite which has strong magnetic qualities. These qualities led to the use in early compasses.
How are magnet made?
Magnets are made by lodestone. If the magnetic qualities of lodestone are passed in a magnetic substance, then it will be a permanent magnet.
What is it called when Earth's magnetic poles chang places?
This is known as magnetic reversal when earth's magnetic poles change places.
What is the magnetic force of this planet called?
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
Is the magnetic field of earth stronger near the middle of the earth or at the bottom of earth?
near both magnetic poles
How would you use the Earth's magnetic field to tell you where on Earth you are?
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
