Given, AB and CD are dipoles kept at an angle of 120 o to each other. Resultant magnetic dipole moment is given by, Resultant magnetic dipole makes an angle 60 o with Y-axis or 30 o with x-axis. Now, torque is given by, Direction of torque is along negative Z-direction. Feb 02, 2011 · I tried answering this previously and had calculated that the moment about the x-axis is 20 Nm, the moment about the y-axis is 100 Nm, and the moment about the z-axis is zero. The resultant moment... the angle α is calculated as above. The law of cosines gives . frome the law sines, we may determine the angle θ which orients R. thuse, Algebric solution By using the x-y coordinate system on the given figure, 7 we may write . The magintude and direction of the resultant force R as shown in Fig, c are then
