Because the inner core of Earth is a solid sphere suspended in the gravitational center of the liquid outer core. Both cores are an alloy made up of mainly nickel and iron. This alloy is conductive and the inner core is spinning at a different rate in the outer core. This difference in angular momentum creates a huge electric dynamo, which in turn creates a strong magnetic field. If and when the core of the earth completely cools to a solid the dynamo effect will cease, and our magnetic field will collapse. If there is any atmosphere that remains at this time, it will be boiled off into space by our suns solar wind. The water will eventually follow the way of the atmosphere and the surface of earth will begin to look like the surface of Mars.

Is earth an electromagnet?
a part of the earths structure causes it to act like an electromagnet
Does the earth's inner core behave like a thick liquid?
No. It behaves like a solid.
What are some true statements for magnets and their poles?
The earth is an electromagnet. It has a north pole and a south pole. Apex: A magnet always has two poles, earth is a elecrtomagnet
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electricity is turned off.
How do you know that earth behaves like a huge bar magnet?
A compass always points north as the south magnetic pole is located at the geographic north pole.
Is earth an electromagnet?
a part of the earths structure causes it to act like an electromagnet
Why does earth behaves like a magnet?
The earth's magnetic properties are due to its molten iron core.
What is that part of the earth that is relatively hot and that behaves as a highly viscous fluid?
The asthenosphere.
Does earth's inner core behave like a thick liquid?
No. It behaves as a solid.
What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
Does the earth's inner core behave like a thick liquid?
No. It behaves like a solid.
What is the source of electromagnet?
An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).
Does a compass behaves as it does because the moon acts as a giant magnet?
No, the earth is itself a huge magnet.
Earth is a what kind of magnet?
Apparently an electromagnet, if that's what you mean, since the current is believed to be the result of currents flowing in Earth's interior.
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
Why Does Gravitational Force Not Act Horizontally?
Because the earth behaves like a magnetic field with the center of the earth pulling everything towards it.... do the math.
What are some true statements for magnets and their poles?
The earth is an electromagnet. It has a north pole and a south pole. Apex: A magnet always has two poles, earth is a elecrtomagnet
