What Is Magnetic Fields
Moving charges are a source of magnetic fields.
"Magnetic Fields" Is the area around magnet that has magnetic lines of FORCE.

This picture demonstrates what occurs when one magnet is placed on paper,and iron filings are sprinkled around it.

Pictured here are two magnets placed on a piece of paper with their like poles facing other, and iron filings are sprinkled around them.

Lastly, this picture has two magnets placed on a piece of paper with their opposite poles facing each other, and iron filings are sprinkled around them.
What Causes the Earths Magnetic Field?
Magnetic Fields are produced by the motion of electrical charges. For example, the magnetic field of a bar magnet results from the motion of negatively charged electrons in the magnet. The origin of the Earth's magnetic field is not completely understood, but is thought to be associated with electrical currents produced by the coupling of convective effects and rotation in the spinning liquid metallic outer core of iron and nickel.
