This is Richard Feynman's take on a simple question,
why do magnets repel each other?
A little more on Richard Feynman. He was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model.
As always:
A scientist is not a person who gives the right answers, but one who asks the right questions.
