Wow. You really, really don't understand the concept. The CME is not a direct arc from the sun to the earth. What propagates through space is a magnetic disturbance. That magnetic disturbance can induce current in wires. The longer and thincker the wire is the more potential that can be created in that wire.
Because it is an instantaneous current and not a constant load the amperage is extremely low. Depending on the length of the wire the voltage can be high.
That is what the claimed threat is. Any ionized radiation will be deflected by the earth's magnetic field.
apparently you are ignorant too. https://www.extremetech.com/extreme/186805-the-solar-storm-of-2012-that-almost-sent-us-back-to-a-post-apocalyptic-stone-age
Suffice it to say, but it’s bad news if the energy and plasma from a big solar flare or CME hits the Earth. Much like a man-made electromagnetic pulse (EMP) weapon, the solar energetic particles strike the Earth with such force that it ionizes the atmosphere, creating a vast cloud of energetic electrons that bounce around inside the atmosphere destroying electronics and fusing conductive wires everywhere. It would probably take out a few satellites in Earth orbit, too.
