electromagnetism
Unified field theory
Electromagnetism is the branch of physics dealing with the relationship between electricity and magnetism—forces that turn out to be aspects of a single phenomenon.
Electric currents generate magnetic fields; changing magnetic fields generate electric currents.
This unity underlies electric motors, generators, radio waves, and light itself.
The course covered electromagnetism and quantum mechanics.
