Nice try, but unfortunately article have few factual mistakes and bias.
First, Earth shield is not just magnetic, but it is complex, magnetic + 100km of thin atmosphere, where most secondary particles just decay with time.
Calculations said, for comparable shield, need approx 6 meters of just water. Sure, it is lot of weight, so other calculations said, interstellar ship (or even martial ship) could use tanks with liquid hydrogen as shield, as they should be huge (for martian ship they should be thousands of metric tons, for interstellar, magnitudes more).
Second, very long text, but not said clear, that after cancellation of Shuttles, AMS-02 was modified, to use permanent magnet instead of superconductor.
