1. The problem statement, all variables and given/known data
A straight segment of a currentcarrying wire has a current element IL where I = 2.70 A and L = 2.60 cm i + 4.40 cm j. The segment is in a region with a uniform magnetic field given by 1.36 T i. Find the force on the segment of wire. (Give the x, y, and z components.) 2. Relevant equations [tex]\theta = tan^{1}(y/x)[/tex] [tex]F = ILBsin\theta[/tex] 3. The attempt at a solution Well I am pretty sure there will be no x or y component because the force will be perpendicular in the z direction. To find the z component I found the angle between the wire and the mag field using: [tex]tan^{1}(4.4/2.6) = 59.421[/tex] After that I thought you are just supposed to plug everything in: [tex]2.7A * .05111m * 1.36 * sin(59.421) = .1615N[/tex] But it's wrong!! I'm not sure what I am doing wrong, the book I am using isn't very good ad explaining. I'm sure it's something simple that I am just overlooking. Thanks, Nick 1.
