Well, under the current models, there are four forces that govern the universe (and therefore us):
1. Gravity
2. Electromagnetic force
3. Weak interaction (beta decay)
4. Strong interaction (atomic nucleus)
What we experience and regularly observe are 1 and 2.
As humans we don’t generate much gravity to speak of. But our construction is, in the end, electromagnetic.
So there’s the magnetic part...doesn’t mean we generate any macroscopic external magnetic field though. 😃
Good post!
