Electromagnetism
Electromagnetism is the study of how electrically charged particles interact and influence one another through electromagnetic fields, force and radiation. This fundamental area of physics investigates phenomena such as electric currents, conductivity, induction, dielectricity, magnetism, and electromagnetic waves including light. In this context, Electromagnetism is a key aspect in understanding high energy physics due to its role in the behavior of subatomic particles like electrons, positrons, protons, and photons. The field explores the intricate relationship between electricity, magnetism and their combined effect on matter and radiation, making it an essential component in comprehending the wider realms of physics and science as a whole.
