I have attached a copy of the question I am having issues with, I can't seem to figure out the equation I have to use to solve this. My lecturer did an example of this but for some reason I can't find it anywhere.
If you cannot figure out the equation - use physics instead, and derive the equation.
What is happening, mechanically and electrically, in the problem?
What sort of law will apply here?

I think I solved the problem. Emf = BLV. And we know that emf will be equal to IR when the current is 0.5A.
