Electrodynamics - Meaning, Definition & English Examples
Electrodynamics is the branch of physics that studies the interaction between electric and magnetic fields and their effects on charged particles. It explains phenomena like light and electromagnetic waves.
Definition:
The study of the interaction between electric currents and magnetic fields.
Synonyms:
electromagnetism, field theory, Maxwell's equations
Part of Speech:
noun
Antonyms:
statics, electrostatics
Common Collocations:
quantum electrodynamics, classical electrodynamics, relativistic electrodynamics
Derivatives:
electrodynamic, electrodynamical
Usage Tips:
Use "electrodynamics" when discussing moving charges and their magnetic effects, not static electricity.
Common Phrases:
Maxwell's electrodynamics, quantum electrodynamics, relativistic electrodynamics
Etymology:
From Greek "ēlektron" (amber) and "dynamis" (power), coined in the 19th century for electromagnetic phenomena.
Examples:
- 1. Electrodynamics explains how electric motors work.
- 2. Students often find quantum electrodynamics challenging but fascinating.
- 3. Maxwell unified electricity and magnetism with his electrodynamics equations.
- 4. Relativistic electrodynamics deals with high-speed charged particles.
