Answer:
It's not a galvanic cell
Because the notation shows that Magnesium has the more negativity in terms of emf, than silver.
Hence electrons flow from Magnesium electrode to silver electrode, inducing current flowing in the opposite direction.
A galvanic cell has Magnesium and Aluminium electrodes, in order for feasibility
