The rectangular loop shown in Fig. is pivoted about the y-axis and carries a current of 15.0 A in the direction indicated.
(a) If the loop is in a uniform magnetic field with magnitude 0.48 T in the + x direction, find the magnitude and direction of the torque required to hold the loop in the position shown.
(b) Repeat part (a) for the case in which the field is in the -z-direction.
(c) For each of the above magnetic fields, what torque would be required if the loop were pivoted about an axis through its center, parallel to the y-axis?
