The Science of Electricity and Magnetism: A Summary
- Electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields, and is one of the four fundamental forces of nature.
- Electromagnetism can be thought of as a combination of electrostatics and magnetism, with the electromagnetic force causing attraction or repulsion between charged particles and magnetic interactions occurring between charged particles in relative motion.
- Electromagnetism is responsible for many of the chemical and physical phenomena observed in daily life, and plays a crucial role in modern technology.
- The study of electromagnetism dates back to ancient times, but it wasn't until the late 18th century that scientists began to develop a mathematical basis for understanding the nature of electromagnetic interactions.
- Maxwell's equations, a set of four partial differential equations, provide a complete description of classical electromagnetic fields and predicted the existence of self-sustaining electromagnetic waves, which make up visible light.
- Theoretical implications of electromagnetism helped inspire Einstein's theory of special relativity, and the field of quantum electrodynamics modified Maxwell's equations to be consistent with the quantized nature of matter.
- The electromagnetic force is one of the four known fundamental forces and the second strongest, operating with infinite range.
- Classical electromagnetism is described by a set of equations known as Maxwell's equations, and the electromagnetic force is given by the Lorentz force law.
- Electromagnetism is compatible with special relativity, which replaced classical kinematics with a new theory of kinematics.
- Nonlinear dynamics can occur when electromagnetic fields couple to matter that follows nonlinear dynamical laws, such as in magnetohydrodynamics.
- There are several plausible choices of electromagnetic units in CGS, including Gaussian, "ESU", "EMU", and Heaviside–Lorentz, with Gaussian units being the most common.
- The study of electromagnetism informs electric circuits and semiconductor devices' construction and has numerous applications in modern technology.
