Question

Consider the four Maxwell equations: 
 Which of these must be modified if magnetic poles are discovered?

Quizplus · Accepted Answer

Maxwell's second equation (Gauss's law for magnetism) states that magnetic field lines must be closed loops with no beginning or end, which is consistent with the assumption that magnetic monopoles do not exist. If magnetic poles were discovered, this equation would need to be modified to account for the presence of magnetic charges. Maxwell's third equation (Faraday's law) governs the behavior of magnetic fields in the presence of changing electric fields, and would not need to be modified if magnetic poles were discovered. Maxwell's first and fourth equations (Gauss's law for electric fields and Ampere's law) are also independent of the existence of magnetic poles and would not need to be modified. Therefore, the correct answer is C) only II and III.
