Maxwell's second equation (in differential form) is expressed as тИЗ├ЧH=J+тИВtтИВDтАЛ. This equation is a generalized version of Ampere's Circuital Law, incorporating Maxwell's displacement current density term to account for time-varying electric fields.

The principle states that a magnetic field can be generated by two sources: a conduction current density J and a time-varying electric field flux density тИВtтИВDтАЛ. By adding the displacement current term, Maxwell ensured the consistency of the equation with the equation of continuity, allowing for the propagation of electromagnetic waves.
Maxwell's second equation explains how magnetic fields are created by electric currents and time-varying electric fields.
The term тИВtтИВDтАЛ is known as displacement current density.
This equation demonstrates that a magnetic field exists even in the absence of a conduction current if the electric field changes over time.
Ensures consistency with the principle of charge conservation.
Predicts the existence of electromagnetic waves in free space.
Does not account for magnetic monopoles (which are explicitly forbidden by Gauss's Law for magnetism).
Mathematical complexity increases with dynamic fields.
Design of antennas and wave propagation systems.
Analysis of capacitors under high-frequency AC signals.
Maxwell's equations are often listed in different orders depending on the textbook; however, the equation involving the curl of H is universally known as the Maxwell-Ampere law.
Option B (Faraday's Law) corresponds to Maxwell's third equation (тИЗ├ЧE=тИТтИВtтИВBтАЛ).
A is correct тАФ Maxwell's second equation represents the Ampere-Maxwell law, which relates the curl of the magnetic field intensity to the conduction and displacement current densities.
Remember the sequence: Gauss(E), Gauss(B), Faraday(E), Ampere-Maxwell(H). A common mnemonic is 'Electro-Magneto-Induction-Ampere'.
