Chapter 7, Problem 21(choose chapter or problem)
Consider the magnetic field B(r) defined by equation (15). As was the case with the electric field in equation (10), it is not obvious that the integrals in (15) converge at all r D. Follow the ideas of Exercise 20 to show that B(r) is, in fact, well-defined at all r, assuming a continuous current density field J and bounded region D in R3.
