A metal ball carries a charge of 4.0 x 10-6 C. An insulating bar whose length is 0.20 m is attached to the ball. The bar is then rotated about an axis perpendicular through its other end with an angular speed of ω = 150 rad/s. (a) Find the current produced by the movement of the charge. (b) Find the magnetic moment of the rotating charge. (Hint: The charge travels around a circle in a time equal to the period of the motion.)
