Well, the article isn't about anything new in Physics, what ever I say here is as old as electricity & magnetism is. The question is whether EMF [The Electro Motive Force (emf), is the external work per unit charge to produce an electric potential difference across two open-circuited terminals.] is CONSERVATIVE OR NON CONSERVATIVE ?
Obviously, conservative and I will not object you.Well what if it's not conservative in a specific situation, How can one explain this paradox? Who can explain it? Read and find out...
