For over half a century, scientists suspected a quiet but powerful electric field might be influencing Earth’s upper ...

Furthermore, an alternating electric field is employed to polarize the passive particles, creating dipole-dipole repulsive forces that help assemble the particles into a specific configuration.

Question 4: Derive the expression for the electric field at a point on the axial line of an electric dipole. Question 5: Using Gauss's theorem, derive the expression for the electric field due to ...
