Primarygun Posted October 20, 2005 Share Posted October 20, 2005 When there are two current-carrying wires are put together facing the same direction on the same plane going through a paper perpendicularly, what will be the magnetic field observed on the paper?

swansont Posted October 20, 2005 Share Posted October 20, 2005 When there are two current-carrying wires are put together facing the same direction on the same plane going through a paper perpendicularly, what will be the magnetic field observed on the paper? The sum of the individual fields, which are given by the right-hand rule (clockwise, for current into the page) and varying as 1/r. Link to comment Share on other sites More sharing options...
Primarygun Posted October 21, 2005 Author Share Posted October 21, 2005 I only knows field lines come from north pole to south pole. For a straight current carrying wire, there's no pole there, so I am not able to figure it out, may you elaborate more? Link to comment Share on other sites More sharing options...
