In fact, at the time of Maxwell's death, his theory of electromagnetic fields was not yet widely accepted or even well known; experts still argued about whether electricity and magnetism propagated their effects via «action at a distance,» as gravity (supposedly) did, or by Michael Faraday's «lines of force» (incorporated by Maxwell into his fields).
But the mystery for physicists is why that force is so puny compared with the electromagnetic force that it doesn't rip that magnet off your refrigerator — we're talking about the pull of an entire planet, after all.
Now these fundamental matter particles interact by means of forces and within quantum mechanics we believe that these forces are mediated by quantum, by particles, and so we have the electromagnetic force mediated by photons which are massless; we have the weak nuclei force mediated by massive particles which are called W and Z and we have the strong nuclear force mediated by massless gluons.
