Light quanta, or photons, and magnetic quanta, or virtual photons, both travel as waves through the electromagnetic field. They propagate at the speed of light and do so at the same distance away from their local source.
In classical electromagnetism, electromagnetic waves are composed of both electric and magnetic fields oscillating perpendicular to each other and to the direction of wave propagation. The electric and magnetic fields are interdependent and propagate together as an electromagnetic wave.
Photons, which are quanta of light, are associated with oscillating electric and magnetic fields. They are the fundamental particles that carry electromagnetic energy and exhibit both wave-like and particle-like properties.
Virtual photons, on the other hand, are particles that arise in the context of quantum field theory when describing electromagnetic interactions. They are considered to be exchange particles mediating the electromagnetic force between charged particles. Virtual photons are not directly detectable and do not travel independently over long distances like photons do. Instead, they exist as virtual particles within the framework of quantum field theory during the interaction processes.
So, both light quanta (photons) and magnetic quanta (virtual photons) travel as waves through the electromagnetic field, propagating at the speed of light and maintaining the same distance away from their local source.
