A magnesium bar still requires tinder. Given that such a critical item and skill takes up so little space, I am amazed people go brain dead for the next step. We have jelly impregnated cotton balls, SPARKLITE tinder tabs, birthday candles, potassium permanganate, charcloth and magnesium. None of these are exactly sufficient to roast that pig from LORD OF THE FLIES. People should carry, at minimum, a few sticks of Fatwood. I say Fatwood, not that overpriced sawdust called Mayawood. I have yet to fail lighting a tinder tab with a Sparklite. I have also yet to fail ingniting a fatwood stick off the tab. FIRE + TINDER + KINDLING + MAINFUEL= warmth and survival. Think about which step most people are weakest at.
