1. A current-carrying loop in a uniform magnetic field is shown in the figure below. The loop is rectangular and made of a single wire of uniform linear density 1 = 146 g/m through which runs a current of I = 78.3 A. The distance between points a and b is 45.5 cm and the distance between b and c is 29.0 cm. The magnetic field points horizontally. The loop is attached to an axle on the left and has a mass of m = 121 g attached to it on the right. What must be the magnitude of the magnetic field in order to keep the system suspended in equilibrium so that the loop is angled at 0 = 23.0° below the horizontal? B m
