A 300-turn wire loop with a 5.0 cm radius is connected to a 0.20-kg pulley by a lightweight rod. The pulley, which has a radius of 3.1 cm, is attached to a 3.7-kg block by a massless rope, as shown in the figure. The loop is in a 0.75-T magnetic field. When no current flows through the wire loop, the plane of the loop is parallel to the magnetic field, and the block attached to the pulley just touches the ground. However, when a 0.83-A current flows through the loop, magnetic forces cause the loop to rotate, which lifts the block off the ground. Calculate the equilibrium angle of plane of the loop relative to the magnetic field. To what height y off the ground is the block lifted? 0 = y = N
