I'll point out you couldn't just park it at L1. If it's deflecting the solar wind, then it's acting as a solar sail. You would need active propulsion to keep it on station.
I was thinking the same thing but you likely have an area to work with however L1 points are unstable as it is and require satellites to alter the courses every once in a while potentially if you use the magnetic field as a light sail slightly in front of the point you'd be balanced between the sun and mars with less active thrust

Assuming the solar wind is constant, you could presumably park it somewhere other than L1. That's certainly not a valid assumption, though, so propulsion is going to be necessary.
