Magnesium ribbon reacts with oxygen present in the air to form a protective and inert layer of magnesium oxide on its surface. This layer is unreactive & prevents the ribbon from burning. Hence, it needs to be cleaned with sand paper before burning it

We rub magnesium beacause magnesium carbonate a basic protective layer is covered on it,we remove this basic layer before burn it in the air.

When exposed to air many metals will slowly react with oxygen in the atmosphere to form metal oxides and magnesium is one of those metals. Like rusting in case of iron, with magnesium, the oxide layer forms a white coating on the outside of the metal that will slow down or interfere with the burning process. Rubbing with sand paper helps to remove this oxide layer due to which burning speeds up.
