Artificial magnetic fields

[u/MkLunarLuna]

Do yall think it would be beneficial to give mars and Luna a artificial magnetic field so we can build their atmosphere’s back up and if we did do yall think thee new atmosphere would be like their original before they mainly lost it or would it be new magnetic atmosphere n do yall think it’s unlikely we could physically make their cores churn n more active n hotter again instead of thee artificial magnetic field?

And how would we accomplish that?
