burning smell from mac

my charger for my 2012 mac book pro broke earlier and won’t close all the way, it open a little and is just staying that way. i went to plug it into my mac and it would go on and off again. it would charge then stop and charge and stop and keep doing that. i plugged my mac into another mac book pro charger to see if it was my mac and it worked fine. i let my charger cool off and plugged it back into my laptop to see what would happen and my mac shut off and there was a pop noise and it smells likes it's burning and won't turn on. i tried to plug it in the other charger to see what would happen and nothing. does anyone know what happened? can it be fixed?
