Chapter 28, Problem 042 The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.78 m long and makes an angle of θ=42.1° with the x axis, and the wire carries a current of 1.21 A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field is given by (a)3.91 kT? (b)3.75 İ T?
