A coaxial cable has an inner conductor of radius a, and outer thin cylindrical shell of radius b. A current I flows in the inner conductor and returns in the outer conductor. The self-inductance of the structure will depend on bow the current in the inner cylinder tends to be distributed. Investigate the following two extreme cases. (a) Let current in the inner conductor be distributed only on the surface and find the self-inductance. (b) Let current in the inner cylinder be distributed uniformly over its cross-section and find the self-inductance. Compare with your results in (a).

Consider a linear long current source lying on the x – y plane parallel to x axis lo-
cated at y = -d. A current of I is flowing in e direction on the current loop. A
loop is also located at the x- y plane with its center at the origin. The loop has a
radius of a. Write the expression for mutual inductance of the described system.

A long coaxial cable (Fig.) consists of two concentric cylindrical conductors
with radii a and b, where b>> a. Its central conductor carries a steady
current i, and the outer conductor provides the return path, (a) Calculate the
energy stored in the magnetic field for a length l of such a cable. (b) What is
the inductance of a length l of the cable?
You want to wind a coil so that it has resistance but essentially no
inductance. How would you do it?
