1. Write down an explicit expression for the vector potential given a current j by following the procedure used above to find a scalar potential.

2. Differentiate the result in 1 to find a formula for diverence free v given its curl everywhere.

3. Put your result of 2 together with the corresponding statement for conservative fields to give a formula for a vector field that vanishes at infinity in terms of its divergence and curl everywhere.
