Therefore, in the near field, there is only storage of energy. Also, since the electric field intensity is much larger than the magnetic field intensity, the stored electric energy is higher than the stored magnetic energy and dominates in the near-field domain. This means the dipole in the near field is essentially capacitive in nature.

6 FAQs about [The area near the dipole is the energy storage area]

Why does a dipole have a minimum potential energy?

Moving the dipole from that minimum potential energy position requires work to be done and thus the potential energy of the dipole is increased with the energy stored in the electric field. With no external electric field there is no potential energy stored and the dipole does not have a preferred direction (minimum potential energy) of alignment.

What is the normal position of a dipole in electric field?

Direction of torque is perpendicular to paper, coming out. The torque rotates the dipole in such a way that the angle θ reduces, when the dipole aligns itself along the direction of electric field, the torque becomes zero. This is the normal position of dipole in electric field.

Why does electric dipole have different potential energy in different direction?
