a: electromagnetism ~
b: gravity
What:
"Electromagnetism is, like gravity, a fundamental force of nature. You may find gravity obvious; you feel it every day. It is what keeps you grounded. Electromagnetism, however, is slightly harder to wrap your head around; charge is less intuitive than mass! You are not surprised when an apple falls from a tree, but when a beam of water is bent in the presence of a glass rod, there is a more magical mood to it."
