Self inductance

  1. Oct 3, 2013 #1
    Consider a solid cylinder of radius R. an varying current of current density δ flows through. what would be self inductance of that cylinder

    What is the context of the question? Is this for schoolwork?

    I think the inductance per unit length is infinite. To get a realistic finite value you need to consider the 'return' conductor carrying the same current in the opposite direction. The easiest case is when this conductor is a cylindrical shell co-axial, but spaced apart from, the solid cylinder.
