A thermite reaction is basically iron oxide (rust) reacting with aluminum to produce molten iron. The reaction is initiated by the heat from burning magnesium ribbon which is placed in the iron oxide/aluminum mixture, this is the fuse

Hey dear.....
HERE'S YOUR ANSWER.
Sometimes, a highly reactive metal is used to displace a metal of lower reactivity from their compounds. These displacement reactions are highly exothermic.The amount of heat evolved is so large that the metals are produced in the molten state. Such reactions are known as THERMIT REACTIONS. For E.g : The reaction of iron(III) oxide with aluminium is used to join railway tracks or broken machine parts.
Fe2O3 + 2Al ——› 2Fe + Al2O3 + ∆
