A rectangular loop consists of 100 closely wrapped turns and has dimensions 0.40 m by 0.30 m. The loop is hinged along the y-axis, and the plane of the coil makes an angle of 30.0? with the x-axis (Figure). What is the magnitude of the torque exerted on the loop by a uniform magnetic field of 0.80 T directed along the x-axis when the current in the windings has a value of 1.2 A in the direction shown? What is the expected direction of rotation of theloop?
