A straight wire segment of length L makes an angle of 27 degrees with respect to the x axis. The wire carries a current of 4.3 A in the direction shown in the figure. There is a magnetic field in the vicinity of the wire which points in the negative z direction with a magnitude given by B=B0(x/L)1, where B0=2.8 T and L=2.96 m. A) What is the x component of the force on the wire segment? I got -2.86 N which was wrong B) If the wire is free to rotate about the z axis, what is the magnitude of the torque on the wire segment? I got 14.9239 N*m which was wrong. Can you please help?
