    Why should there be a "but" in your post? Why shouldn't two different things just be different?

    Hi,
    In EM waves are just energy, So chargeless. [Lorentz transformation of a moving charged particle]
    PS: EM waves contains only the fields (electric and magnetic).

    The charge is simply the source of the EM wave. Once the wave is propagating, why should it still have the charge?

    Let me put it another way:
    Sound waves are created by vocal cords, but sound waves don't have vocal cords.
