There is a rectangular loop of 10 cm x 5 cm. The loop has an axis of rotation that is about the z axis. Initially it is suspended forming an angle of 50o with respect to the negative y-axis as shown in the figure: 500 The mass of the long segments is 0.2 kg each and that of the short segments is 0.1 kg each. A current runs through the loop in the direction shown in the image and has a magnitude of 15 A. Calculate the magnetic field B (magnitude and direction) to which the loop must be exposed, so that it initiates a rotation movement in counterclockwise (on the xy axis) with an angular acceleration of 1.2 rad/s2.
