Questions and Answers

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?

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?

If magnetic monopoles were ever found, the law would have to be modified.

How can Gauss's law for magnetism be written in two forms?

<p>Gauss's law for magnetism can be written in two forms, a differential form and an integral form, which are equivalent due to the divergence theorem.</p> Signup and view all the answers

What is the basic entity for magnetism according to Gauss's law for magnetism?

<p>Rather than 'magnetic charges', the basic entity for magnetism is the magnetic dipole. If monopoles were ever found, the law would have to be modified.</p> Signup and view all the answers
