Because Magnesium, like other highly reactive metals, is much more easily oxidized than most fuels for fires.
The Magnesium can essentially "steal" oxygen from the carbon dioxide
CO2 + 2Mg --> 2MgO + C

The first carbon dioxide portable fire extinguisher in the USA was made by Walter Kidde & Co., Inc. in 1924.
why should uou not touch the horn or pipe when using carbon dioxide extinguisher
Carbon dioxide
Carbon Dioxide
Magnesium burns in carbon dioxide because, when heated, the oxygen in the carbon dioxide is able to bond with magnesium and produce an oxide. Carbon, or soot is formed as a resulting by-product. 2Mg + CO2 ----> 2MgO + C
It is the propellant used to force water out of the extinguisher.
It doesn't. The soda solution mixes with the acid and the chemical reaction FORMS carbon dioxide gas, which pressurizes the extinguisher.
Clacium + Magnesium=> Carbon Dioxide + Water
Magnesium carbonate
