Electromagnetic force

Electromagnetic force

(Science: physics) One of the fundamental forces of interaction which influences charged entities. In quantum field theory, the electromagnetic force is mediated by particles of exchange called (virtual) photons.

photons are massless and travel at the speed Of Light c. The electromagnetic force obeys an inverse square law, which makes sense because it is mediated by particles that have an infinite lifetime (special-relativistically, time stops in a frame moving at c when observed from a non-moving frame).

Ion uptake in freshwater teleosts?

... the outside and potassium ions to the inside of the cell. The pump is electromagnetic because more positive charges are pumped to the outside than ... ions must diffuse through this surface layer. Thus this electromotive force is no longer proportional to the hydrogen ion concentracion because ...
