Unit 4 Day 11 – Gauss’s Law for Magnetism Magnetic Flux & the magnetic Equivalent of Gauss’s Law Gauss’s law for Electricity Gauss’s Law for Magnetism Consequences of Gauss’s Law of Magnetism

Magnetic Flux

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

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

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)
