Though this is formally equivalent to the electrostatic case of Coulomb's law, I must emphasize this is only formal. This is because the magnetic scalar potential was only employed as a tool to compute magnetic fields, with -divM as the equivalent "magnetic charge", this "magnetic charge" is...

The magnetic potential can be defined as a scalar or a vector, the magnetic potential (as is its electric counterpart) is used classically as a tool to compute the magnetic field, so depending on the problems as long as one still gets the correct B-field, it can be defined in a non-unique way...

It depends on the level of understanding, I think Sakurai has done a good job balancing mathematics and intuition. One can do a highly mathematical exposition for a grad QM book, butr I guess what one treasures in QM is a little intuitive understanding.

My review for Sakurai's QM: http://www.textbookreview.blogspot.com/ What's your opinion on using this book?

Well I hope another better textbook will come up and replace Jackson.
