About this Site
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!
A Simple Model for Atomic Nuclei: The Deformed Sphere and its Multipole Moments
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.
The Magnetic Field of an Infinite Wire
One of the basic problems of magnetostatics is the infinite wire. Using the several symmetries of the current distribution we will be able to not only find the magnetic field - we will also verify the "right-hand rule".
Literature: Jackson, Griffiths, ...
Effective learning takes several steps. As it is for example important that you discuss the problems on the site with your colleagues, it is also essential that you have a more or less complete reference at hand - you will be working with it and give you insights for much longer than the duration of a course.
Contribute: Share your Knowledge!
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 Plasmonics: Antennas for THz Spectroscopy
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
The Disadvantages of Solar Energy
Before we can all admire the new and exciting green future, let us have a clear and analytic look on what the disadvantages of solar energy are. Let us also find out what these disadvantages mean practically.
