heavy ion collision magnetic field (IMAGE) DOE/Brookhaven National Laboratory Caption Collisions of heavy ions generate an immensely strong electromagnetic field. Scientists investigate traces of this powerful electromagnetic field in the quark-gluon plasma (QGP), a state where quarks and gluons are liberated from the colliding protons and neutrons.
