Which of the following equations can be used to show that magnetic field lines form closed loops?
E) none of these

Question

Quizplus · Accepted Answer

The equation shown in option B is the mathematical representation of Gauss's law for magnetism which states that the magnetic flux through any closed surface is zero. This implies that magnetic field lines must form closed loops as they cannot start or end at a single point or go on indefinitely. The other options either show Faraday's law or Ampere's law which do not directly relate to the closed loop nature of magnetic field lines.
