[QUOTE="DODGEVIPER13, post: 4517348, member: 389722"] [h2]Homework Statement [/h2] A conductor that is 2 m long and is caring a current of 3 A is placed parallel to the zaxis at a distance ρ0= 10 cm as shown in Figure 2. If the magnetic field in the region is cos(ϕ/3)Up Wb/m^2, how much work is required to rotate the conductor one revolution about the z-axis? [h2]Homework Equations[/h2] W=Fd torque=m x B where m=magnetic moment m=IS [h2]The Attempt at a Solution[/h2] Well I tried formula for surface area of an elliptical cylinder pi(Major radius)(minor radius) which is S but I don't have B. am I going about it wrong? Anyways once I did this I was planning on multiplying it by the current given. And then multiply that by the length of cylinder 2m which will give me the torque force which I can then find the for d=distance traveled in one revolution and multiplt that by the torque to give me work.
