These are the sort of theoretical questions that are important to me for ~mumblemumblereasons~, but which are a little tricky to find answers for, because they're not the sort of thing we concern ourselves with. But I am hoping perhaps some of you have the sort of knowledge and enjoyment of speculation that might let you weigh in and help me out.

1. If Earth had no magnetic field, could smaller objects on the ground still display magnetism? In other words, is the magnetism of objects, such as magnetic minerals or magnets themselves, tied to the planet's magnetism, or is there an inherent magnetism within the object itself that would work independent of any larger magnetic field? I believe the answer is yes, but I'm hoping someone can confirm that for me.

2. In addition, if Earth suddenly lost its magnetic field, would our electronics be affected?

3. If you were in a place that was completely flat, by which I mean a plane, not even on a curved surface such as the Earth, what limits would be placed on how far you could see? If there was nothing in your way, no buildings or anything, would you be able to see something big, say an Olympus Mons sized mountain, that was a thousand miles away? More? Or would dust, atmosphere, pollution, or whatever else combine to blur the sight of distant objects?

4. Are there things that we take for granted that would change if we lived on a planet that didn't rotate? For example, without a planetary coriolis effect, the movement of clouds and air pressure would be different, giving us different weather patterns. I know that it's fairly improbable that a planet wouldn't rotate to some degree, but this is theoretical.

My thanks in advance if you can shed any light for me. Though really, you ought to see a dermatologist. Shedding light can't be natural.
