I didn't have 1st year physics, so this was very informative for me.

Maxwell 1 + 2: Field per surface area. The asymmetry between magnetic fields and electrical fields is that magnetic ones have a total field of zero; that is, al magnetic lines loop back on themselves.

Maxwell 3: The principle behind power generating turbines.

Maxwell 4: The principle behind electrical motors.

To be honest, I didn't even know you can condense it into four equations. I was only exposed to the history of electromagnetism, not the latest expression thereof.
