1. The problem statement, all variables and given/known data 2. Relevant equations μ0 In,e = ∫B⋅ds 3. The attempt at a solution I really don't how to approach this question at all. Do you have to integrate counterclockwise around the loop every time? If the field was decreasing as y decreased, would you integrate CW or is it still CCW? Why does μ0 In,e = ∫B⋅ds being >0 mean that it must be out of the page.
