What is the net flux or circulation integral through a closed surface in 'Magnetism and Matter'?

medium MCQ Class 12 · Physics · Magnetism and Matter
  1. It is proportional to the total enclosed source magnitude divided by permittivity/permeability
  2. It is always infinite regardless of boundary conditions
  3. It depends entirely on the outer geometric shape of the surface
  4. It is always negative
Answer
It is proportional to the total enclosed source magnitude divided by permittivity/permeability

The correct answer is It is proportional to the total enclosed source magnitude divided by permittivity/permeability — The shape of the closed Gaussian surface does not affect the net enclosed flux.

Step-by-step solution

  1. Gauss's Law relates boundary flux to the total enclosed charge .
  2. The shape of the closed Gaussian surface does not affect the net enclosed flux.
