2. Magnetic Flux

3. The Electric Case
Gauss’s Law for the electric case, remember is:

4. Gauss’s Law for Magnetism
We can write a similar relation for the magnetic case, however, there are no isolated magnetic charges (monopoles) exist. Therefore:
This is Gauss’s Law for Magnetism

5. Consequences of Gauss’s Law of Magnetism
Gauss’s Law for Magnetism tells us that as many lines of magnetic flux enter an enclosed surface, as leave it
Since magnetic monopoles do not exist, there are no sources or sinks for magnetic field lines, unlike E-Fields
Therefore, magnetic fields must be continuous (no beginning or end)
