Most of the problems I've worked on involve wires of small radii, however, if DC current flows within large radii of conductive wires, would I need to use current density ##J## for calculating the magnetic field at a point ## r > R## instead of ##I## if it we're known?
With relevance to a wires with large radii, would ampere's law change? Or still valid regardless of large or small radii? Also, in relation to that matter, does the Lorentz force alter with the change of geometry of the wire(e.g large radius, shorter lengths etc...)?
