Does Electric Field & Magnetic Field need a medium to travel?

Electric field is created around the flow of electrons,and electrons
need a conductor to flow through. Magnetic field is created by virtual
photons and can travel through space. Such is the Sun ,planets fields
can literally go to infinity. Sun's magnetic field gives us the Northern
lights. Jupiter magnetic field is stronger than the Sun's but it is so
much further away and photons obey the inverse square law. Our moon has
a field but it is only 1% of Earth's Trebert

The thick and robust crust of our physically dark Selene/moon is
magnetic and otherwise paramagnetic, whereas the core has a minimal
amount of iron and it is extensively offset or pulled towards Earth,
perhaps leaving some extra portion of that lunar interior as hollow.
