The figure shows a rectangular, 19-turn coil of wire, of dimensions 11 cm by 6.2 cm. It carries a current of 0.085 A and is hinged along one long side. It is mounted in the xy plane, at an angle of 30 to the direction of a uniform magnetic field of magnitude 0.67 T. Find the (a) x, (b) y, and (c) z components of the torque acting on the coil about the hinge line. Hinge line (a) Number i Units (b) Number i Units (c) Number i UnitsA horizontal power line carries a current of 4730 A from south to north. Earth's magnetic field (71.5 pT) is directed toward the north and is inclined downward at 66.0 to the horizontal. Find the (a) magnitude and (b) direction of the magnetic force on 95.0 m of the line due to Earth's field.
