Magnetic fields arise from permanent magnets and electric charges in motion. Magnets can occur naturally (such as the Earth's magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges. A typical representation of this can be seen in the figure below.
