I know what is an electric field. It exerts a force over distance between electric charged particles.
I know what is a magnetic field. It exerts a force over distance between particles with magnetic dipole moments.
I don't know how to show the interaction over distance between EM radiation and what? The absorption of a photon by an electron hardly one can call a force over distance. Maybe the expression EM field is a comprehensive term for electric and for magnetic fields? The claimed EM field in QM seems not to be a field in the meaning of influence nor force of what's ever.
