Homework Statement
it is a long question so I have attached the question and picture
Homework Equations
I feel it is more theory based, which I explain below.
3. The attempt at a solution
I am unsure- but I would think it is from B to A for part B, as using the RHR, if the coils are wrapped this way and the flow is down through that column. But for part c) I am really unsure and I have tried reading multiple websites about solenoids, transformers and inductance but cannot find a clear answer. If b is B to A, then is the current in C in the opposite direction- opposing what is being produced by the primary, so it would be C to D in the diagram? Any help or clarification would be greatly appreciated. It was given as an extra problem though without a solution and it is really bothering me to not understand the concept behind it.
