Additional questions related to the differential form of Ampere’s law. As you will note Amperes law in differential form is particularly useful in determining the current density and current given a magnetic field. Trying to obtain B or H knowing J or I is not so simple due to the unknowns (B or H) being in derivatives. Nevertheless B and H can be determined with a high degree of symmetry is present and only one derivative remains in the curl process. 1) Given a magnetic field, ( 29 φ π ˆ 2 / 2 a Ir H = is present inside a conductor of radius a ,
