Question

Explain the gauss law for magnetic fields​

Answer 1

Explanation:

In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero, in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist

Answer 2

Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero, in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist.

The Gauss’s law for magnetic fields in integral form is given by:

(48)¶

∮Sb⋅da=0,

where:

b is the magnetic flux

The equation states that there is no net magnetic flux b (which can be thought of as the number of magnetic field lines through an area) that passes through an arbitrary closed surface S. This means the number of magnetic field lines that enter and exit through this closed surface S is the same. This is explained by the concept of a magnet that has a north and a south pole, where the strength of the north pole is equal to the strength of the south pole (Fig. 35). This is equivalent to saying that a magnetic monopole, meaning a solitary north or south pole, does not exist because for every positive magnetic pole, there must be an equal amount of negative magnetic poles.

Gauss’s law for magnetism states that no magnetic monopoles exists and that the total flux through a closed surface must be zero. This page describes the time-domain integral and differential forms of Gauss’s law for magnetism and how the law can be derived. The frequency-domain equation is also given. At the end of the page, a brief history of the Gauss’s law for magnetism is provided.
