The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.20 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 9.0 A in the direction shown. Figure 1 of 1 Part A Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0∘ with the yz-plane. Express your answer in teslas.
