27.68 .. The rectangular loop Figure P27.68 shown in Fig. P27.68 is pivoted about the y-axis and carries a y current of 15.0 A in the direc- 15.0 A tion indicated. (a) If the loop is in a uniform magnetic field with magnitude 0.48 T in the +x-direction, find the magni- tude and direction of the torque 8.00 cm 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 mag- netic fields, what torque would be required if the loop were pivoted about an axis through its 30.00 6.00 cm Z. Figure P27.69 center, narallel to the y-axis?
