Figure 28-50 shows a wood cylinder of mass m = 0.246 kg and length L = 0.0755 m, with N = 23.0 turns of wire wrapped around it longitudinally, so that the plane of the wire coil contains the long central axis of the cylinder. The cylinder is released on a plane inclined at an angle θ to the horizontal, by the plane of the coil parallel to the incline plane. If there is a vertical uniform magnetic field of magnitude0.702 T, what is the least current i (in A) during the coil that keeps the cylinder from rolling down the plane?
