A circular coil of radius 10 cm and with 125 turns is initially oriented perpendicular to a uniform magnetic field of strength 2.50 mT directed out of the page. The wire carries a current of .250 A. a) Sketch the situation. b) Indicate the direction of the magnetic moment of the coil. c) What is the torque on the coil? d) if the coil was nudged so that it rotated with the left side of the coil into the page and the right side out of the page, is there a torque on the coil now? e) What will be the resulting motion of the coil? f) At what point will the torque on the coil be maximum? f) What is the maximum torque on the coil?
