2. (20 points) Four oscillating electric dipoles of equal strengths p = po cos(wt) are located at fixed locations and directions according to the figure (all in xy plane), at the distance a from the origin. Determine the magnetic field radiated by the dipoles in the far zone. - sin ✰ = sin cos of + cos e cos ŷ= sin sin of + cos 0 sino + cos 2 = cos of - sin 0 0
