Easier to do big, with lower light intensity, and fewer "expensive" materials.

So go big. They'll figure out the best way to approach it.

So the "shield" will have to be WAY forward.
About 43 minutes forward:

43 minutes is the distance of the L1 away from
Mars as far as the local solar wind speed is
considered. Or 3.5 light-seconds as far as the
solar light is concerned.

The magnetic field does not stop light, only charged particles. So solar wind speed, is what needs to be figured in.

The article you linked to is from 2011, and it's about a totally
different issue. It's about an early warning system for solar winds, so
putting a satellite at the L1 would encounter the solar wind 43 minutes
before Mars itself does. But due to the higher speed of light, which
gets to Mars in 3.5 seconds, you have 43 minutes - 3.5 seconds of early
warning about it.

The issue here is not about early warning, but about redirecting the
solar winds completely from Mars. So early warning really has no bearing
on anything here, except that if the parameters of the magnetic shield
need to be adjusted, you have about 7 seconds of turn around time to
react from Mars.
