The 10-turn loop of wire shown in the figure (see attachment) 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 non-magnetic axle through the center. A .050 kg mass hangs from one edge of the loop.
(a) What is the magnetic moment m of this loop?
(b) What is the torque caused by the hanging mass?
(c) Calculate the magnetic field strength that will prevent the loop from rotating about the axle?© BrainMass Inc. brainmass.com March 4, 2021, 11:09 pm ad1c9bdddf
