A galvanometer frame with an area of 1 cm2, containing 200 turns of thin wire, is suspended on an elastic thread and located along the magnetic field lines with an induction of 15 mT. When a current of 5.0 μA was passed through the frame, the frame rotated 15°. At what angle will the frame rotate at a current of 7.5 µA? What is the torsional modulus of the thread?
