Electrostatic vs. Electromagnetic: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 26, 2023
Electrostatics deals with stationary electric charges, while electromagnetism involves electric charges in motion, creating magnetic fields.

Key Differences

Electrostatics focuses on the study and behavior of electric charges at rest. It involves forces, fields, and potentials arising from static electric charges. Electromagnetism, on the other hand, encompasses both electric and magnetic fields, especially when charges are in motion. It deals with the interplay between electric currents and magnetic fields.
The principles of electrostatics are governed by laws like Coulomb's law, which describes the force between static charges. Electromagnetic phenomena are explained by Maxwell's equations, which unify the concepts of electricity and magnetism into a single theory. These equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents.
Electrostatic effects, such as the attraction or repulsion between charged objects, are most noticeable when objects have a significant amount of static charge. Electromagnetic effects, in contrast, include phenomena like the generation of magnetic fields around electric currents and the induction of currents by changing magnetic fields.
In electrostatics, the electric field is described as emanating from static charges, with field lines beginning or ending on these charges. In electromagnetism, electric and magnetic fields are dynamic, with magnetic fields typically depicted as closed loops, not beginning or ending, and electric fields induced by changing magnetic fields.
Applications of electrostatics include electrostatic precipitators and photocopiers. Electromagnetic applications are more diverse, encompassing electric motors, generators, radio waves, and the entire spectrum of electromagnetic radiation, from radio waves to gamma rays.
