6 A square coil and a rectangular coil are each made from the same length of wire. Eachcontains a single turn. The long sides of the rectangle are twice as long as the short sides.Find the ratio Tsquare /Trectangle of the maximum torques that these coils experience in thesame magnetic field when they contain the same current.The coil in the figure below contains 409 turns and has an area per turn of 3.00 x 10° m2.The magnetic field is 0.25 T, and the current in the coll is 0.27 A. A brake shoe is pressedperpendicularly against the shaft to keep the coil from turning. The coefficient of staticfriction between the shaft and the brake shoe is 0.84. The radius of the shaftis 0.013 m. What is the magnitude of the minimum normal force that the brake shoe exertson the shaft?NTwo long, straight wires are separated by 0.12 m. The wires carry currents of 4.0 A inopposite directions, as the drawing indicates.0.030 m0.120 m0.060 m(a) Find the magnitude of the net magnetic field at the point A.(b) Find the magnitude of the net magnetic field at the point B.T
