Understand the ingenious methods scientists will use to reveal the primordial magnetism – if it exists.
As you sit reading this article, you will be surrounded by magnetic fields. If you have a reading lamp, there will be a field emanating from its power cable. Your mobile phone’s battery creates another magnetic field, as does the Earth beneath your feet.
All these magnetic fields are generated by electrical charges in motion. In the cable and phone, electrons are flowing around the circuits. In Earth’s core, liquid iron is rotating, while in stars such as the Sun there are loose elementary particles moving within the plasma.
Magnetic fields reach deep into space. Field lines
