# Maxwell's Second Equation

**Formula:**`∮B⋅dA = 0`

## Introduction to Maxwell's Second Equation

Maxwell's second equation, also known as Gauss's Law for Magnetism, describes how the magnetic flux through a closed surface is always zero. In this formula, ** B** represents the magnetic flux density and

**represents the differential area element. The dot product between**

*dA***and**

*B***results in the total magnetic flux through the surface, and according to the equation, this total flux is always zero.**

*dA*## Parameter usage:

`fluxDensity`

= magnetic flux density`surfaceArea`

= surface area

## Output:

`result`

= 0

## Data validation

The magnetic flux density and surface area should be greater than zero.

## Summary

Maxwell's second equation forms a fundamental part of electromagnetism and is essential in understanding the behavior of magnetic fields.
