A solid conductor occupies the cylindrical region p< b, 0 < z< h, where b = 6 mm and h = 20 m. A potential difference of 0.16 Volts between the ends at z = 0 m and z = 20 m drives a steady current in the direction az, and this produces a magnetic field intensity inside the conductor given (in units of A/m?) by Н- Hop'as; Ho = 4 x 105. Hint: read the full question and decide what order to solve the parts in. They don't necessarily have to be solved in order. (a) Find the total resistance between z = 0 and z = h. ANSWER: R = 0 (b) Find a formula involving c for I(c), the current flowing the region where p < c, assuming 0 < c< b. ANSWER: I(c) = A (c) Find a formula involving c for J(c), the current density at any point where p = c, assuming 0 A/m2
