I'm having trouble with this homework problem!! Current & Magnetic Field!!! This problem deals with current and the magnetic fields around these 2 parallel wires. The question is listed below, as is the link to the picture. Thanks SO Much for your help!!! http://i597.photobucket.com/albums/tt59/JMoore4116/PHY232--Ch31--3-18.jpg If that one doesn't work, try this one: http://s597.photobucket.com/albums/tt59/JMoore4116/?action=view¤t=PHY232--Ch31--3-18.jpg 3.18 Two long parallel wires are separated by a distance of 2.00 m. The two points P1 and P2 divide that distance into three equal parts. Each wire carries a current in the same direction. The current I2 is 3.00 A, as shown in the illustration, and the current I1 is "tuned" so that the strength of the magnetic field at the point P1 is zero. (a) What is the strength of the resulting magnetic field at P2? (b) Suppose the current I1 were re-tuned to produce zero magnetic field at P2. What would be the resulting magnetic field at P1?
