Correct me if I'm wrong.
Without earth's magnetic field we wouldn't have electricity, right?
Because sunflares and cosmic particals would cause EMP strikes on our power grid and 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 in space and on Mars survive or even work if those places are unstable environments where there's no protection against cosmic particles?
Keep in mind if the magnetic field of the earth flips our devices and power grid wouldn't work either.
I also found this in an article
However, if the magnetic field gets substantially weaker and stays that way for an appreciable amount of time Earth will be less protected from the oodles of high-energy particles that are constantly flying around in space. This means that everything on the planet will be exposed to higher levels of radiation, which over time could produce an increase in diseases like cancer, as well as harm delicate spacecraft and power grids on Earth.
Not necessarily. That's not the right type question.
Without the earth's magnetic field, life on earth would probably not exist. The earth's magnetic field has important properties of stopping particles from cosmic rays and solar winds. It also allows for the ozone layer that protects the Earth from ultraviolet waves.
If electronics and electronic devices did exist in this type if environment, some would survive. This all comes down to engineering tolerances and the characteristics of the elements used in these electronics.
Engineers design, build and test devices (especially spacecraft and medical devices) to withstand ionizing radiation, electromigration, and other electrical failures. Note that just cause a device can survive in this type situation doesn't minimize the fact that it's total life can't be shortened.
Not really. They would still work. How would they not work in that specific scenario?
Yes, that is mostly true. Remember that some devices would be able to survive in this type of environment. But ask yourself this, how can the Earth's magnetic field degrade? -Hint: It can't.
