Question
I know that for ab the magnitude=0 and the direction of the magnetic force is zero force, I believe the direction of magnetic force bc is negative x, but I can't find the magnitude for it, or for cd, help.
In the figure above, the cube is 39.0 cm on each edge. Four straight segments of wire--ab, bc, cd, and da--form a closed loop that carries a current I = 5.80 A in the direction shown. A uniform magnetic field of magnitude B = 0.0200 T is in the positive y-direction. Determine the magnitude and direction of the magnetic force on each segment. (Please give the magnitudes to three decimal places.) I know that for ab the magnitude=0 and the direction of the magnetic force is zero force, I believe the direction of magnetic force bc is negative x, but I can't find the magnitude for it, or for cd, help.Explanation / Answer
F_ab=ILB sin=0 [=0]
F_bc=ILB sin=0.04524 [=90]
F_cd=ILB sin=0.04524 [=45,L=2a]
F_da=ILB sin=0.0640 [=90,L=2a]
