A rectangular coil consists of N = 120 closely wrapped turns and has dimensions a = 0.400 m and b = 0.300 m. The coil is hinged along the y axis, and its plane makes an angle θ = 30.0° with the x axis (figure). (a) What is the magnitude of the torque exerted on the coil by a uniform magnetic field B = 0.690 T directed in the positive x direction when the current is I = 1.20 A in the direction shown? N · m (b) If you are looking downward from the positive y direction, what is the expected direction of rotation of the coil? clockwise counterclockwise
