SUMMARY
The discussion focuses on determining whether three given vector fields are electrostatic or magnetic. The first vector field, F1(x, y, z) = A (9yz ex + xz ey + xy ez), is identified as electrostatic due to its curl being zero, indicating no time-varying magnetic field. The second and third vector fields, F2(r,∅,z) and F3(r,θ,∅), require further analysis using divergence and curl properties. Key principles discussed include the divergence of electric fields (div E = ρ / ε0) and the magnetic field divergence (div B = 0), which is essential for identifying magnetic fields.
