## Homework Statement

A long, straight wire of radius a has current density J = J0e−β(α−ρ)uz where β is a

constant and ρ < α. Determine B inside and outside the wire.

## Homework Equations

J=I/((pi)a^2)

B=(μIρ)/(2(pi)(a)^2)

## The Attempt at a Solution

Here is what I did B=(μρ/2)J0e^(-β(alpha-ρ))
