Editing Gauss's Law (Magnetic): (section)

== Mathematical Formulation ==

=== Integral Form ===
<math>
\oint_{\text{closed surface}} \vec{B} \cdot d\vec{A} = 0
</math>

Where:
* <math>\vec{B}</math> is the magnetic field vector (in tesla, T),
* <math>d\vec{A}</math> is a vector representing an infinitesimal area on the closed surface, pointing outward.

This means that the net magnetic flux through any closed surface is always zero.

=== Differential Form ===
By applying the divergence theorem to the integral form, we obtain the differential form:

<math>
\nabla \cdot \vec{B} = 0
</math>

This states that the divergence of the magnetic field is zero everywhere.
