Science Friday: Earth is a giant iron magnet

Earth is a giant iron magnet

Earth’s core is solid iron.  Around this inner core is a layer of liquid iron. The interaction between the liquid and solid iron is responsible for generating electrical currents and a powerful magnetic field.  The magnetic field is in alignment with the Earth's rotation and extends all the way into space.
