Reality of the electromagnetic field.

  1. Jul 16, 2012 #1
    Hi! I'm currently reading 'An Introduction to the Philosophy of Physics, Marc Lange' where he is arguing about the reality of the electromagnetic field etc. While reading I caught myself in not having the concept of what that makes something real in place. How would one define something as a physical -real- thing?

    What would make the electromagnetic field real?

    What does the author say about this? I haven't read this book, but it seems to me he'd have to define it to talk about it.
