Unlike other exams, the AP Physics C exams also had 5 options that test-takers could choose from rather than the typical 4. This was changed in an announcement made by College Board in the February 2024 regarding changes to their AP Physics courses for the 2024–25 school year onward, which explained that the multiple choice sections would ...
There are various mathematical descriptions of the electromagnetic field that are used in the study of electromagnetism, one of the four fundamental interactions of nature. In this article, several approaches are discussed, although the equations are in terms of electric and magnetic fields, potentials, and charges with currents, generally ...
Weber electrodynamics is a theory of electromagnetism that preceded Maxwell electrodynamics and was replaced by it by the end of the 19th century. [1] Weber electrodynamics is mainly based on the contributions of André-Marie Ampère, Carl Friedrich Gauss and Wilhelm Eduard Weber.
Andrew Warwick (2003): "In developing the mathematical theory of electricity and magnetism in the Treatise, Maxwell made a number of errors, and for students with only a tenuous grasp of the physical concepts of basic electromagnetic theory and the specific techniques to solve some problems, it was extremely difficult to discriminate between ...
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

In mathematical physics, in particular electromagnetism, the Riemann–Silberstein vector [1] or Weber vector [2] [3] named after Bernhard Riemann, Heinrich Martin Weber and Ludwik Silberstein, (or sometimes ambiguously called the "electromagnetic field") is a complex vector that combines the electric field E and the magnetic field B.
The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles.
