MCQ
Calculate the surface integral of a magnetic field over a surface.
  • A
    Maximum
  • B
    Minimum
  • C
    Zero
  • Equal to its magnetic flux through that surface.

Answer

Correct option: D.
Equal to its magnetic flux through that surface.

he Gauss’s law states that the surface integral of a magnetic field over a closed surface is always zero. But the surface integral of a magnetic field over a surface gives magnetic flux through that surface.
