Part A Consider a long coaxial cable made of two coaxial cylindrical conductors that carry equal currents I in opposite directions (see figure). The inner cylinder is a small solid conductor of radius a. The outer cylinder is a thin walled conductor of outer radius 6, electrically insulated from the inner conductor. Calculate the self inductance per unit length of this coaxial cable. (L is the inductance of part of the cable and l is the length of that part.) Due to what is known as the "skin effect", the current I flows down the (outer) surface of the inner conducting cylinder and back along the outer surface of the outer conducting cylinder. However, you may ignore the thickness of the outer cylinder. I Express your answer in terms of some or all the variables I, a, b, and Ho, the permeability of free space to

Magnetic resonance imaging instruments use very large magnets that consist of many turns of superconducting wire. A typical such magnet has an inductance of 40 HH. When the magnet is initially powered up, the current through it must be increased slowly so as not to "quench" the wires out of their superconducting state. One such magnet is specified to have its current increased from 0 AA to 150 AA over 230 minmin. Part A What constant voltage needs to be applied to yield this rate? Express your answer with the appropriate units.
