Gauss Law in Magnetism
We can write Gauss’s law for magnetostatics as `intB.dA=mu_0m`, where, `intB •dA`. is the magnetic flux and m is the net magnetic pole strength inside a closed surface.
It was found that, magnetic flux through a closed surface is always zero, thus we reach at a conclusion that magnetic monopoles do not exist. A bar magnet always attain north-south poles no matter how many times it is cut into pieces.
The number of magnetic field lines passing through a surface area normally is called
Options:
(a) magnetic field
(b) electric field
(c) magnetic flux
(d) electric flux
