According to a 2023 lecture titled What Physicists Don't Know About Electromagnetism given by the theoretical physicist Hans Schantz [162] and based on the comparison of textbooks Electromagnetic Theory by Julius Stratton and Classical Electrodynamics by John Jackson, Schantz argues "today's physicists who are educated using curriculum out of ...
Matthew Nojimu Olanipekun Sadiku from the Prairie View A&M University, Cypress, TX was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) in 2013 [1] "for contributions to computational electromagnetics and engineering education". He is a co-author of the textbook Fundamental of Electric Circuits with Charles K. Alexander.
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 ...
The theory provides a description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible. For small distances and low field strengths, such interactions are better described by quantum electrodynamics which is a quantum field theory .
Such a hypothesis would be essentially equivalent to suggesting a 'theory of nature' in which all stable particles (or aggregates) are merely nonradiating charge–current distributions whose mechanical properties are electromagnetic in origin. The nonradiation condition went largely ignored for many years.
A theory of electromagnetism, known as classical electromagnetism, was developed by several physicists during the period between 1820 and 1873, when James Clerk Maxwell's treatise was published, which unified previous developments into a single theory, proposing that light was an electromagnetic wave propagating in the luminiferous ether.

In the same decade, the systematic theory for the method of moments in electromagnetics was largely formalized by Roger Harrington. [14] While the term "the method of moments" was coined earlier by Leonid Kantorovich and Gleb Akilov for analogous numerical applications, [15] Harrington has adapted the term for the electromagnetic formulation.

Hertz vectors, or the Hertz vector potentials, are an alternative formulation of the electromagnetic potentials. They are most often introduced in electromagnetic theory textbooks as practice problems for students to solve. [1] There are multiple cases where they have a practical use, including antennas [2] and waveguides. [3]
