does light contributes to earth magnetic as it is an electromagnetic wave?

No earths magnetic field is due to earth core.
Light is an electro-magnetic wave. It does not mean that an electro magnetic wave causes any change in the magnetic or electric properties of the space.
It is merely a disturbance in the electric or magnetic field through the space.
