Unformatted text preview: B field in terms of μ o I o /2 π r o = B o and find the angle the B field points. (Recall how you did this for the E field.) Wire 2 has twice (2I) the current of wire 1. Current 1 is out of the page and current 2 is into the page. Show all your reasoning including vector components for C. Please be neat. I o 1 2 2I o r o r o r o r o r o C A B...
