I have my final answer now: Electromotive force (e.m.f.) is the force that drives electrons around the circuit, so you would expect an electric current to be impossible without an e.m.f. However, when certain metals are cooled below their “critical temperature” they exhibit a property known as...

I see, that is actually a better answer than what I had in mind, thank you very much

Thank you all for helping, my problem is resolved now. (I don't know how to edit the thread to say it is resolved)

Ok thankyou, I will research that and hopefully it will solve my problem.

Homework Statement Can there be an electric current without an e.m.f.? (i noticed my mistake in the title, it should be e.m.f. not EMF)I was given this question and I don't know how to answer it, any help would be greatly appreciated
