Something I've never been able to understand. So correct me if I'm wrong.

Without earth's magnetic field we wouldn't have electricity, right?

Because sunflares would cause EMP strikes on our electric devices and they would shut down. Right?

Even our skin wouldn't be able te handle te sunlight.

How does electric devices such as satellites and robots on Mars survive or even work in an unstable environment where there's no protection against cosmic particles?

Keep in mind if the magnetic field of the earth changes our devices wouldn't work either.
