The magnetic field can easily be noted if you hang a magnet from a piece of string, or use a compass; the compass needle is also magnetic. The idea is for the compass or hanging magnet to be able to freely rotate.
Since the north pole of the compass needles points north, you can conclude that the south pole of planet Earth is towards the north. Remember that opposite poles attract each other.

The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
What does Earths magnetic axis do not do with its rotational axis?
intersect
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
The earths magnetic shield has?
existed since the planet cooled
What effects do Earths magnetic field and ozone layer have on Earth's ability to support life?
bob
What evidence is there that the earths magnetic fields move?
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.
Is the earths gravity the same as the magnetic field if not what is the difference in effects?
i dont know its aload of bumf go away :p
Why Describe how fossils can provide evidence of how environmental conditions and life have changed during earths history?
hi
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Is Lanthanum magnetic?
which of the list of rare earths are magnetic
How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
Volcanic rock shows that some layers have magnetic fields that are aligned opposite to Earths This evidence BEST fits which hypothesis?
Sea floor spreading / plate tectonics. Also magnetic reversal in the past.
