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 4.2 kg block by a massless rope. 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 0.76 A current flows through the loop, magnetic forces cause the loop to rotate, which lifts the block off the ground. Calculate the angle the plane of the loop rotates relative to the magnetic field. How high off the ground is the block lifted
