Electromagnetic Existence

Is it possible for the human body to create an electromagnetic field? Originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.

Answer by Jack Fraser, Master’s Physics, University of Oxford, on Quora:

I want you to imagine me punching you hard, in the nose.


Trust me, it’ll help make this description much more fun! Imagine you said something rude about my mother, if it helps.

Did that hurt? I’m no fighter, but I imagine it probably did.

Why did it hurt?

Well my fist connected rather rapidly with your face, and that ought to do it.


But what does it mean to “connect”, or “touch”?

Our bodies are made up of cells, which are made up of atoms. And atoms are… well they’re mostly empty space.

An atom is a centralized region of extreme density and positive charge (the nucleus), surrounded by a region of standing ‘probability waves’ which describe the wave function of the electron.

In other words, an atom is basically a ‘fuzzy’ (technical term) ball of charges.
