“Science” is huge, though as far as I understood it, most money is in medical sciences / pharmaceutical, chemical, physics and electrical/RF stuff. I’m strictly into medical sciences, and in particular long-term mammalian health. I couldn’t really tell you what I exactly work on cus you could google my name in 5 seconds. I’m an author on 9 peer-reviewed publications now and I’m working / collaborating on several manuscripts which will be submitted at some point.

I like the recent advances in DNA/RNA sequencing technologies. It has become so cheap that it is almost a mundane lab technique. Its cheapness also is leading to creative ways to apply the technology which were previously prohibitively expensive. Even on a consumer level you can get your whole genome read at high quality for like 500€, it is really astonishing. You could use that data now and in the future whenever new discoveries are made.

I dunno how magnets work. It is some sort of permanent charged state that can interface with electrical fields. It makes no sense to me but of course it has a good physics explanation.
