Magnesium powder and ribbon are relatively stable in air at normal conditions, probably because of thin protective layer of oxide. However, ribbon can burn in air with blinding light and powder gives self-burning (i.e. not needing external oxygen sources like air) mixtures with many common substances, some of them explosive. Moreover, burning ...
Details
Normally one demonstrates magnesium burning by getting it started in the Bunsen flame, and then removing it so that it burns in air with a blinding white light. The product is a white smoke. This product can be collected by burning the magnesium under an inverted beaker, showing it is a solid, a white ash — MgO.
Details
Combustion reaction also known as burning is a exothermic chemical reaction which means heat energy is always released. When Magnesium in its metallic state reacts with oxygen in a combustion reaction, a colour change is observed. A white powder called Magnesium Oxide is formed and heat is released.

Details
Fire is what we call the heat and light produced when things burn. Magnesium reacts with oxygen to make a compound called magnesium oxide. 2Mg + O 2---> 2MgO. The bright light results because this reaction produces a lot of heat. When the magnesium gets really hot, it emits energy in the form of light (heat is also how the sun produces light).
Details
burning magnesium powder. Monitor carefully for flare-ups and smother these as necessary. Use self contained breathing apparatus (SCBA) or approach fire from upwind due to dense white smoke (magnesium oxide) produced. NOTE: If small amounts of magnesium powder are burning, these may best be handled by allowing them to burn
