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.

What else can I help you with?
What on the ocean floor is evidence that earths magnetic field changes?
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.
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
How have Earths magnetic poles reversed many times during Earths history?
Earth's magnetic poles have reversed many times in the past due to changes in the Earth's molten outer core. As the molten metal moves, it generates the Earth's magnetic field. Over time, this movement can cause the magnetic field to weaken, flip, and establish a new polarity. The process of pole reversals is a natural part of the Earth's geophysical history.
How does the magnetic orientation of lava layers demonstrate reversals of earths magnetic field?
When lava cools and solidifies, magnetic minerals within it align themselves with Earth's magnetic field. By studying the orientation of these minerals in lava layers, scientists can track changes in the Earth's magnetic field over time. Reversals of the Earth's magnetic field are reflected in lava layers as bands of alternating magnetic orientation.
At which location is earths magnetic field the strongest?
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
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.
Are earths magnetic poles located on its axis?
No, Earth's magnetic poles are not located exactly on its geographical poles. The magnetic poles are located slightly off-axis and can shift over time due to changes in the Earth's magnetic field.
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 forms when earths magnetic field changes direction?
When Earth's magnetic field changes direction, it results in a phenomenon known as geomagnetic reversal or magnetic flip. This process involves the magnetic north and south poles switching positions. These reversals have occurred throughout Earth's history and have been recorded in the rock record.
What on the ocean floor is evidence that earths magnetic field changes?
Evidence that Earth's magnetic field changes can be found in the alignment of magnetic minerals in rocks on the ocean floor. As magma solidifies into new rock, the magnetic minerals within it align with the current magnetic field direction. By studying the alignment of these minerals in rocks of different ages along the ocean floor, scientists can track changes in the Earth's magnetic field over time.
Minerals in igneous rocks can show the direction of earths?
The Earth magnetic field changes approximately every 200,000 thousand years.
Is earths core a source of earths magnetic field?
Yes.
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.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
Switch in direction of earths magnetic north and south poles?
Magnetic Reversal
