PHYS208 Fundamentals of Physics II

Hint for Ch. 30, 47P

Use a circular amperian loop of radius r centered about the axis of the coax cable. The magnetic field found from application of Ampere's law will be (mu0 ienc)/(2 pi r). The field in each region will then depend on the current enclosed by the amperian loop with that radius.
