Solution
Given,
number of turns in the coil, N = 29
area of the coil, A = 0.11 m * 0.062 m = 0.0068 m^2
current in the coil, i = 0.15 A
angle in the xy plane, ? = 30°
magnetic field, B = 0.40 T
Since, the action of the force is perpendicular to the plane of the coil and is located a distance x away from the hinge then the torque has magnitude
? = NiAB cos? = 0.010 N.m
since ? = rxF the direction of the torque is -y . in unit vector notation the torque is
? = 0
? =( -0.010 N.m )j
?= 0
