(7) [5 points] A straight wire with steady current I = 3.5 A runs through a region of space with a uniform magnetic field of the form 13\" = 0.17? 0.321" + 0.21]? measured in tesla. (a) Align the wire with the x, y, and 2 directions. Which directions give the maximum and minimum force per unit length? Write a vector expression for the force per unit length on the wire in each orientation. (b) Now consider the straight wire in any possible direction. Describe the orientation for which the force per unit length on the wire is minimum, and maximum. You may answer (b) in words, but you should also mention if there are degenerate orientations (different orientations that give the same result)
