• A coaxial cable has an internal inductance that is triple the external inductance .If the inner conductor radius is 6.0mm solve the following: 
• i. Propose the outer conductor radius 
• ii.Assuming the space between the conductors is filled with a nonmagnetic material, determine the inductance per unit length,L'(L prime) 
• iii.Instead of the space between the conductors is filled with a nonmagnetic material now it is filled with Cobalt µr=250, evaluate the inductance per unit length,L'(L prime), compare with the answer in (ii) and justify 
• iv.Let treat this coaxial as infinitely long coaxial with inner conductor radius of 6.0mm is placed along the z-axis.If the conductor carries current I=5A in the -z direction,determine H at(0,5.0mm,0) and (0,6.5mm,0)
