Question: A 20-turn rectangular coil with side l = 20 cm and w = 10 cm is placed in the yz plane as shown in Fig.

A 20-turn rectangular coil with side l = 20 cm and w = 10 cm is placed in the y€“z plane as shown in Fig. 5-34 (P5.6).

20-turn coil Figure P5.6: Rectangular loop of Problem 5.6.

(a) If the coil, which carries a current I =10 A, is in the presence of a magnetic flux density B =2 x10-2 (x + y2) (T), determine the torque acting on the coil.
(b) At what angle is the torque zero?
(c) At what angle is the torque maximum? Determine its value.
