A long straight cable of radius a = 0.100 m lies along thex-axis. Inside the cable the current density is constant and hasmagnitude J = 5.00 ( Ampere m-2 ). The current densityis directed along the + x direction. Let s be cylindricalradius.
i. What is the current running through the cable between radius0 and s?
ii. What is the magnetic field as a function of s inside thecable?
iii. What is the total current running through the cable?
iv. What is the magnetic field as a function of s outside thecable?
