- pjc50 6y agoTrick question (or trick answer): depends what you mean by "electricity", which is one of those questions that's simple to ask but collapses into a pile of details on closer inspection. The electric field and magnetic field are tied together in the manner described by Maxwell's equations. This results in "electromagnetic waves", which are indeed carried by photons in free space. It is often helpful to look at the fields as being the real "electricity", or at least use the lumped approximation we call "current", and this brings various charge carriers along with it. Electrons are the common charge carrier, but ions can carry charge (e.g. in batteries), and in semiconductors we use "holes", which are the absence of an electron. Not an anti-electron, just the space where it's supposed to be.
