SUMMARY
The discussion focuses on calculating the magnetic field both inside and outside a cylindrical wire carrying current I, with charge density j and radius R. The Biot-Savart Law and Ampère's Law are identified as the primary equations for this analysis. The magnetic field inside the wire is determined to be B = μ₀I / (2πr), while the magnetic field outside the wire is given by B = μ₀I / L, indicating that the magnetic field outside the wire is independent of the wire's radius.
