I didn't really know how to word this question, but what's confusing me is this: I was researching "what is an electron" and I read in many places that "an electron is an excitation in a magnetic field". But what does this mean? I thought that an electron is just a particle with mass and charge, and when a charge moves it creates a magnetic field. What does "an excitation in a magnetic field" mean?
Also does this mean that an electron could be created out of nowhere from a magnetic field? (I know mass cannot be created or destroyed but e=mc^2 so the mass would come from the energy)
Thanks!
