Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism.
Static friction is recognised as a self-adjusting force because it wants the objects to remain at rest not move. Hence, if an external force is applied, the static friction force will be equal to the magnitude of the external force, until it surpasses the threshold of motion.
