- For time varying fields, the electric field is not conservative. Why? Explain withmathematical substantiations.3. Biologists often study the patterns of migratory birds by using radar (1-10 GHz electromag- netic waves) to track their flight. To check whether radar waves influence the birds' flight, researchers tracked the birds visually, both with the radar on and with it off. The 9 GHz radar waves had an intensity of 400 W/m² at 250 m. What was the amplitude of the electric field at this distance? (The experiments showed that the radar did not affect the birds.)electromagnetisma The polarization vector in a dielectric tube of inner radius r; and outer radius r. is P = Po(a, 2x + ây3y). The axis of the dielectric tube defined by zoz20 coincides with the z-axis. a) Determine the equivalent polarization surface and volume charge densitites. b) Show that the total bound charge is zero.
