You can show that the Earth has a magnetic field by looking at a magnetic compass.
The north end of the compass points to the north magnetic pole, and does so everywhere on Earth. It does this by aligning itself to the Earth's magnetic field. If there weren't a magnetic field, then a compass needle would not point to any consistent direction.

How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
What is the region of the earths magnetic field?
magnetosphere
How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
How a magnetic compass can be used to find directions on Earths surface?
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
How do you know that there is not a huge permanent magnet at the earths core?
For one, the magnetic field changes continuously; this is not consistent with a permanent magnet.
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
Minerals in igneous rocks can show the direction of earths?
The Earth magnetic field changes approximately every 200,000 thousand years.
How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
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.
Is earths core a source of earths magnetic field?
Yes.
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
