A.4 A harmonic oscillating electric dipole with the form p = Po cos(-wt) e, is placed at the origin. Sufficiently far from this dipole the electric field has the form: E(r) w²po sin cos(kr - wt) 4π€0C² -Co, r where is the polar angle (between the position vector r and the z axis) and k = w/c. Using Maxwell's equations, find the corresponding magnetic field.
