BREAKING: New Phase of Matter

4:13 Interestingly, while neutrons don't have a net charge, they _do_ turn out to have a magnetic moment, and are affected by magnetic fields (but only a really small bit). As far as I understand it, this is because it's quarks (one up and two down) individually have charges. And because the quarks aren't all exactly in the same "location", the charge isn't exactly 0 everywhere.
