That’s gonna be very difficult, restarting Mars’ dynamo is going to require some god-like amount of power. We don’t even know what powered the string dynamo it had 4 billion years ago; all we know is that there was a good magnetosphere, and then that collapsed and for a while a much weaker secondary dynamo took over, until that collapsed as well.
To get back an earth like dynamo, we’d need to do something crazy like re-melt huge parts of Mars’ insides in such a way to generate a flow structure that would remagnetise the planet.
I suspect it may very well be easier to cool down Venus than to restore Mars’ magnetic field when it comes to terraforming.
Planets are kind of big, that’d require lots of power in a very large area.
We’d probably be able to get more done by putting a few sattelites between Mars and the sun and generating the necessary repelling field there. Still requires a huge amount of energy, but doesn’t require it to also be distributed around a planet.

Rather than restarting Mars’s internal magnetic field, could we build a solar or nuclear powered artificial magnetic field?

Something like a swarm of satellite drones at the Mars-Sun L1 point?
That’s what was thinking of. No idea if it’s even feasible but it’d help concentrate the power requirement to a more manageable position.
Nah man what we need is a solar wind-powered artificial magnetic field. Make the problem pay for its own solution.
