How does a 'open surface' of a closed loop look like?

  1. Jul 11, 2011 #1
    im on the topic of electricity and magnetism, and came across walter lewin's lecture.

    i cannot visualise how the 'open surface' of this solenoid will look like

    is the open surface a riemann surface? or something else?

    thanks

    I believe the correct terminology is helicoid.

    A Riemann surface is something else entirely. I'm not a mathematician, but as I understand it, a Riemann surface is just a way to visualize different branches of a function and how they are related to each other.
