A long, straight piece of copper pipe has an inner radius of Ra = 6.7 mm and an outer radius of R, = 7.9 mm. The pipe carries a uniform current density of J = 1,800 A/m2. Deter- mine the magnitude of the magnetic field B midway between the inner and outer radii of the pipe. For the limits check, in- vestigate what happens to the magnetic field B at the midway point as R0. (Note that the location of the midway point will shift in response to R, changing.)
