Could a Planetary core, Mars for example, be restarted with a high enough quantity of nuclear detonations deep in the crust?
If it could, this could be a means to start the terraforming of mars, since an active core creates a magnetic field that protects an atmosphere. It could also solve a problems of ridding the world of nuclear weapons, since they are of no use to us.

The bigger issue with mars is that it’s too far away form the sun to support a warm enough environment for us. Solving that problem is much more important.
Also I would have to imagine you may be inflicting some pretty severe radiation issues detonating enough nukes there.
I am not a physicist, but I would think that 1., there is not enough fisseable material in this solar system to supply enough energy to not only liquify the core but also to start its rotation to create the magnetic field which is essential to deflect harmful solar radiation, and 2., even if you had enough nukes to do it, it would most likely destroy the planet instead of ‘restarting’ the core.
Now, you have to realize that nuclear explosions have little effect on geology, and that nuclear fallout would be negligible, since it would be contain within the crust. I am also assuming that mars has a semi-solid outer core.
And, on a side note, the explosives need not be nuclear, they could be a projected fissile material that has not been invented yet. You have to understand that this would not be remote feasible nowadays.
Sounds like a recipe for a planet-busting natural disaster.
Your efforts would be better spent building electromagnetic shield generators, TBH.
