Best ResponseYou've already chosen the best response.0Sketch the field lines for the magnetic fields associated with the currents shown in the diagram below. (The dots and crosses show the direction of the currents.) WARNING: The drawing is a a bit crappy. sorry. :/ dw:1397260188233:dw

Best ResponseYou've already chosen the best response.1Hi! Do you know that the magnetic field "spins around" a wire? Well, the direction of the field at a point ((due to one wire)) is always perpendicular to the imaginary line that connects it to the wire. But perpendicular could be two ways. dw:1397261007941:dw

Best ResponseYou've already chosen the best response.1Right!! Right hand rule. What you do is you take you're thumb. You point it in the direction of the current. Then you look how your fingers are curled. The magnetic field has that same curl!dw:1397261214896:dw

Best ResponseYou've already chosen the best response.0ahh now i understand! :) what does that arrow in between the dot and the cross represent?

Best ResponseYou've already chosen the best response.1You'll need to put these together or reapply these concepts for you're bigger picture! :) The big arrow, here?dw:1397261722560:dwThat's because the electric fields add, there, to be EXTRA strong! Between two of the same kind, however, the field CANCELS because they're in opposite directions. It's like \((1)+(1)=0\)
