A long straight cable of radius a = 0.100 m lies along the x-axis. Inside the cable the current density is constant and has magnitude J = 5.00 ( Ampere m-2 ). The current density is directed along the + x direction. Let s be cylindrical radius.
i. What is the current running through the cable between radius 0 and s?
ii. What is the magnetic field as a function of s inside the cable?
iii. What is the total current running through the cable?
iv. What is the magnetic field as a function of s outside the cable?
