Electromagnetic force

The electromagnetic force is a fundamental force carried by photons. The electromagnetic force enables everything that has to do with electricity and magnetism. It is a more general form of several more familiar forces. For example, it is responsible for the attraction and repulsion between magnets (the Lorentz force), and the attraction between positive and negative charges (the Coulomb force, also known colloquially as opposites attract).

The Coulomb force is implemented in Elementary Craft. Two charged particles placed next to each other will be attracted or repelled, depending on their charge. Two electrons will be repelled since they have the same charge; an electron and a proton will be attracted since their charges are opposite (- and +, respectively).

The electromagnetic force is the most important force in our everyday life. Aside from gravity, any force you are familiar with will be some form of the electromagnetic force. The force you feel when pushing something or pulling a rope, friction, the normal force that keeps you on your chair, ... They all arise from electrons repelling each other, and are therefore electromagnetic forces at their core. On top of this, the electromagnetic force holds atoms together, so without it there would be no matter as we know it. This last fact is referenced in Elementary Craft when crafting atoms: photons must be added in the recipe, since they carry the electromagnetic force.
