Was this your only attempt?
Also, how effective was that magnetic shield?
With that level of realism that was my only attempt yes.
For the magnetic shield it hasn't been tested in real conditions, so I can't say how efficient it is
The idea was to recreate an artificial magnetosphere around the station to deflect most of the radiations. This would have been done with superconductive electromagnets spreaded around the station.
The advantage is that it would shield a large area around the station, even the astronauts in EVA would benefit from it, and it would be much lighter than a lead screen or any sort of passive shield. Because it's made of supraconductive materials, it consumes no electricity. You would only need power to start the system, and once it's running, it costs nothing to maintain.
The drawback is that the superconductive materials must be kept cold enough, so it would require some good heat management. Also, those shields only deflect charged radiations, they have no effects on neutrons, X and gamma rays.
Charged radiations are the biggest danger though, and the core of the station was reinforced to provide an additional protection in case of a punctual event of more intense radiations.
There was a similar concept studied, it was called SR2S (Space Radiation Superconductive Shield)
