In physics, Gauss's law for magnetism states that the magnetic field B has divergence equal to zero. What does this statement imply about the nature of the magnetic field?
In physics, Gauss's law for magnetism states that the magnetic field B has divergence equal to zero. What does this statement imply about the nature of the magnetic field?
This statement implies that the magnetic field is a solenoidal vector field, and it is equivalent to the statement that magnetic monopoles do not exist.
What is the name commonly used for Gauss's law for magnetism?
What is the name commonly used for Gauss's law for magnetism?
The law is also called 'Absence of free magnetic poles' and is referred to as the 'transversality requirement' because for plane waves it requires that the polarization be transverse to the direction of propagation.
What would have to be modified if magnetic monopoles were ever found?
What would have to be modified if magnetic monopoles were ever found?
If magnetic monopoles were ever found, the law would have to be modified.

Study Notes
Gauss's Law for Magnetism
- One of the four Maxwell's equations that underlie classical electrodynamics
- States that the magnetic field B has divergence equal to zero
- Equivalent to the statement that magnetic monopoles do not exist
- Basic entity for magnetism is the magnetic dipole, rather than "magnetic charges"
Forms of Gauss's Law for Magnetism
- Can be written in two forms: differential form and integral form
- These forms are equivalent due to the divergence theorem
Other Names for Gauss's Law for Magnetism
- Also called "Absence of free magnetic poles"
- Referred to as the "transversality requirement" because for plane waves it requires that the polarization be transverse to the direction of propagation
