Circular Current Loop Given: F i n d : cm a 1 . 4 ? 17 N ? A i 29 . 1 ? T B 46 . 0 ? x 0 ? y 90 ? z 21 A circular loop of radius a = 4.1 cm consists of N = 17 turns. The current is I = 1.29 A per turn. When viewed looking down the x -axis, the current in the nearest portion of the loop is moving in the direction of the arrow shown in the diagram. (a) Calculate the magnitude of the magnetic moment of this loop. A spatially uniform magnetic field of strength B = 0.46 T points in the + z direction. Let denote the angle between the plane of the loop and the x - y plane. (See diagram.) (b) What is the magnitude of the torque on the loop when = 0° ? (c) What is the magnitude of the torque on the loop when = 90° ? (d) Calculate the components (magnitude and algebraic sign) of the torque when
