Why rubbing of magnesium ribbon with sand paper is done to make better contact with oxygen?

Magnesium, when exposed to air, spontaneously forms a surface oxide of the type known as " passivating", which remains attached to the underlying metal and prevents the oxidation of the underlying atoms by blocking the access of oxygen molecules to them. Sandpaper removes this passivating oxide layer temporarily.
