Magnetic Field due to long cylindrical conductor | Ampere's law | Applications of Ampere's law

Ampere’s law: Applications
Consider a cylindrical conductor with radius R carrying a current I, which is uniformly distributed over the cross-sectional area of the conductor.
Find the Magnetic Field B inside, and outside of the Cylinder.
