WebMagnetic fields 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. WebMay 10, 2016 · The magnetic field is thought to be produced largely by an ocean of molten, swirling liquid iron that makes up our planet’s outer core, 3000 km under our feet. Acting like the spinning conductor in a bicycle dynamo, it generates electrical currents and thus the continuously changing electromagnetic field.
