What direction will mg+2 ions move

The Vm outside the cell is 0, the Vm inside the cell is 40 mV. If the outside concentration of Mg+2 is 30 mM, and the internal concentration of Mg+2 is 3mM, what direction will Mg+2 ions move if a Mg+2 ion channel is opened? For a monovalent cation, the collection of constants in the Nernst potential is 61.5 mV at 37?C

The equation I’ve been using is as follows:

log(out/in)*valence*Nernst Potential

Will the Mg+2 ions move into or out of the cell? Why?
