The 10-turn loop of wire shown in the figure(Eigure 1) lies in a horizontal plane, parallel to a uniform horizontal magnetic field, and carries a 2.0 A current. The loop is free to rotate about a nonmagnetic axle through the center. A 50 g mass hangs from one edge of the loop. Part A What magnetic field strength will prevent the loop from rotating about the axle? Express your answer to two significant figures and include the appropriate units.
