A belted magnum has a belt just above the extractor groove on a cartridge case.(7mm mag, 300 win mag, etc...) and until recently, if it did'nt have a belt, it was'nt a mag(there are a few new mags that have no belt). The belt is there, if I remember correctly, because it was believed it was necessary to reenforce the casing.

The belt was originally there to prevent the round from being chambered in a rifle not designed for magnum pressures. Also, the first magnums headspaced off of the belt, though most recent calibers headspace off the shoulder like conventional ammo.
Here's the only handy pic I have of a belted magnum. This happens to be a pic someone posted of a .450 Watts Magnum (510gr bullet) next to a .223 cartridge: -Troy |

Troy, that was the first level headed and correct response I've ever seen to that particular question.
