Our intention for the site is plain and simple: provide electrodynamic problems with solutions. We hope that the information may help one or the other to understand electromagnetism. We believe that the best way to achieve this is to solve problems and have their solutions at hand. We also take the chance to supply additional information in the background section for most of the problems. This might be an explanation of a related research topic or more in-depth information. We hope you enjoy your path to understand electrodynamics!
We will calculate the first three multipole moments of a deformed charged sphere. Such a charge distribution is often used to model nuclei and understand their stability. The rotational symmetry of the problem will ease our computations significantly.
We believe that enhancing the learning experience of students all over the world is a very nice goal. If you agree and ask yourself what you could do to motivate and inspire a lot of people, find out about the several big and small ways to contribute to problemsinelectrodynamics.com!
Graphene is a two-dimensional material with extraordinary properties. Its tunable conductivity makes the material a prime candidate for sophisticated light-matter interactions. We will see how graphene antennas can be used to dictate a molecule's emission frequencies
