Theoretical and experimental status of magnetic monopoles

The Tevatron has inspired new interest in the subject of magnetic monopoles. First there was the 1998 DO limit on the virtual production of monopoles, based on the theory of Ginzburg and collaborators. In 2000 the first results from an experiment (Fermilab E882) searching for real magnetically charged particles bound to elements from the CDF and DO detectors were reported. This also required new developments in theory. The status of the experimental limits on monopole masses will be discussed, as well as the limitation of the theory of magnetic charge at present.
