[QUOTE="rohanlol7, post: 5043112, member: 547648"] [B]1. The problem statement, all variables and given/known[/B] Two long parallel vertical wires 0.3m apart are. ' placed east-west of one another. The current in the westerly wire is 30A and on the other 20A. The horizontal component of the Earth's magnetic flux density is 2*10^-5. Find the force per unit length on each wire. (The answers are 0 and 1mN but I don't know why) I calculated the force on each wire due to the earth. Then I calculated the force due to the wires. Thesr 2 forces are perpendicular so I used pythagoras to find resultant but my answer was wrong [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] [/QUOTE]
