Highlights the physical relevance of magnetically charged black holes.

Provides insights into black hole physics within string theory.

Abstract

In these lecture notes from Strings `91, I briefly sketch the analogy between two dimensional black holes and the s-wave sector of four dimensional black holes, and the physical interest of the latter, particularly in the magnetically charged case.
