Self inductance and superconductivity?

  1. Mar 27, 2012 #1
    1. The problem statement, all variables and given/known data
    So in Walter Lewin's Electricity and Magnetism video series:
    http://www.youtube.com/watch?v=UpO6t00bPb8&feature=relmfu

    At around 10:00 he says that the resistance in the self inductance is zero because self inductance is superconducting material. However is it possible to have resistance? Are all self inductances superconducting? Also could someone please briefly explain how self inductance works, I know it is a constant but how can you define it intuitively. Is it a property dependent on the material? If it is high it can fight current better but how and why?

    Thanks!
