Unformatted text preview: r < ρ < R . A current I fows in the positive z-direction in the inner conductor, and returns via the outer conductor. The current density in a given conductor is uniForm. Use Amp` ere’s law to ±nd the magnetic ±eld (i.e. magnetic fux density) v B in the regions (i) ρ < s , (ii) s < ρ < r , (iii) r < ρ < R , (iv) ρ > R . Show your work....
