So there was a question on this sheet in my biology class which asked what main force is responsible for the movement of dyes (these dyes had a formal charge and were all water soluble, and were small molecules). I answered electromagnetism. This was marked wrong and he said it was wrong because they aren't like magnets, it is more of an attraction to a large electric charge. I could just be stupid but is that not what electromagnetism is? The interaction of charged particles, magnetic fields and electric current?... Did he just not know what electromagnetism was or am I in the wrong here?
