Loop variables

    Loop variables: A line of force or flux that is closed to form a loop.

    Can a Photon be a line of force or flux that closes to form a loop?

    A photon is not a "line of force", whatever that is supposed to mean.

    Well I guess as the Photon travels it leaves a trail, unless I've been taking the diagrams of wavelengths to literally. So would you say a Photon is instead a line of flux?

    It does not.
    Yes, way to literally.
    No. A photon is not a line of anything.

    So I guess that means then that Photons can not circle around and form loops. There again recently this news story came along 'Photon Mobius Strip' http://www.pbs.org/wgbh/nova/next/physics/mobius-strip-made-light/

    Would you say this is a closed loop?

    Good to know I have been to literal with wave length diagrams :)

    Edit: I genuinely just remembered this news story, I'm not trying to play ace cards up my sleeve here, I'm not trying to catch people out like a detective or lawyer.

    The photons don't form a circle. The polarization as function of space can be Möbius-like.

    Awesome, well thank you, my question has been answered.
