A stationary circular wall clock has a face with a radius of 20 cm. Six turns of wire are wound around its perimeter; the wire carries a current of 1.5 A in the clockwise direction. The clock is located where there is a constant, uniform external magnetic field of magnitude 67 mT (but the clock still keeps perfect time). At exactly 1:00 P.M., the hour hand of the clock points in the direction of the external magnetic field. (a) After how many minutes will the minute hand point in the direction of the torque on the winding due to the magnetic field? (b) Find the torque magnitude.
