1.	Which of the following is not a consequence of Gauss’s law?(a) The magnetic poles always exist as unlike pairs of equal strength(b) If several magnetic lines of force enter a closed surface, then an equal number of lines of force must leave that surface(c) There are abundant sources or sinks of the magnetic field inside a closed surface(d) Isolated magnetic poles do not existI got this question during an interview.The above asked question is from Magnetism and Gauss’s Law in section Magnetism and Matter of Physics – Class 12
Answer» The correct option is (c) There are abundant sources or SINKS of the MAGNETIC field inside a closed surface Explanation: Gauss‘s law INDICATES that there are no sources or sinks of the magnetic field inside a closed surface. In other words, there are no FREE magnetic charges. HENCE, magnetic monopoles do not exist.
