[QUOTE="darkprior, post: 5474652, member: 594118"] [h2]Homework Statement [/h2] Hello, I have this problem: Four long straight parallel wires are placed in vacuum according to the picture, the distance between each wire is a = 20 cm. Through each wire flows electric current I = 20 A in the specified direction. What is the size and direction of magnetic induction in the middle of this system? What is the size and direction of the force acting on one meter of the bottom left wire? [h2]Homework Equations[/h2] - [h2]The Attempt at a Solution[/h2] [ATTACH=full]187783[/ATTACH] I drew the line of forces following the Ampere's right hand law, and also the vectors of magnetic inducion of each wire: [ATTACH=full]187784[/ATTACH] now my answer is how do I compute the size of the resulting induction, and my second question is how do I find out the force acting on 1 meter of the lower left wire? Thanks in advance for advices [/QUOTE]
