elektrodynamikken
Elektrodynamikken (electrodynamics) is the branch of physics that studies the interactions of electric charges in motion with electric and magnetic fields. It describes how these fields propagate, how they interact with matter, and how charged particles move under the influence of fields. Classical electrodynamics forms the core, while quantum electrodynamics provides a quantum description of radiation and light.
Central to classical elektrodynamikken are Maxwell's equations, which relate electric fields, magnetic fields, charges, and currents.
Historically, key milestones include Faraday’s induction, Ampère’s law with Maxwell’s correction, and the unification of electricity,
Applications of elektrodynamikken are widespread. They include electric power generation and distribution, motors and generators, transformers,
