Okay. Lets say you have a coil. You drop a magnet through it, which induces an emf (please explain what exactly an emf is). So, somehow Faraday's Law of Induction comes into play (please explain this law to me). Now you have an incoming and outgoing flux, right (I have no idea what this means)? I'm guessing that the incoming and outgoing flux are equal but opposite. Am I correct? What are the units of a flux? Why are the fluxes equal, that is, if they really are? Please help me.
