Electronic – What are the consequences of not having a magnetic field in the atmosphere on electronics

electromagnetismmagneticsspace

Electronics super-noob here! (I did EE in school but have managed to forget practically everything since, to an alarming degree!).

I'm wondering how the field of electrical engineering and electronics would be affected if humans, say, colonized any of the planets that have no magnetic fields?
I understand that without a magnetic field in the atmosphere, humans would be more easily exposed to harmful radiation. As far as technology goes, how would things be affected?

You can still created magnetic fields in space by creating moving electric fields, right?
Would normal electro-mechanic forces works the same way? Is there any consequence for radio technology or satellites? Obviously, humans have sent probes into the vacuum of space that send data back, so I understand that it works, but I'm curious if there's any different considerations.

What technology would stop working on a planet with no magnetic field (besides compasses)?

There are quite a few man-made electronic devices attached/landed on celestial object with weak/almost no magnetic field, both operational and deprecated. The celestial object include, but are not limited to Mars, Moon, Venus, Titan, few asteroids, as well as a number of satelites and probes that are just floating in space with no external source of magnetic fields other than the far-away Sun.

No problem. Everything works as expected in regard to the magnetic fields.

Then again, the Earth's magnetic field can be quite useful in some unexpected manners. For example, some satelites use it to generate torque for attitude control
