I tell my students that if they can discover a magnetic monopole, then they will receive a Nobel Prize in Physics. An article published recently in Science discusses experiments that seem to have uncovered the elusive magnetic monopole. Why is this important? Why is this news not quite as exciting as you might think?

I was looking at search terms that lead people to this website from Google and stumbled across this one: “the work done by the magnetic field on the charged particle during the semicircular trip.” Someone obviously was interested in how much work a magnetic field could “do”, and Google was kind enough to point them [...]
