What does the term "electromagnetism" refer to?

The term "electromagnetism" specifically refers to the interaction of electric currents with magnetic fields. This fundamental phenomenon is based on the principles established by the relationship between electricity and magnetism, becoming one of the four fundamental forces of physics.

When an electric current flows through a conductor, it generates a magnetic field around it. Conversely, when a magnetic field changes around a conductor, it can induce an electrical current within that conductor. This reciprocal relationship is fundamental to many technologies, such as electric generators, motors, and transformers, which operate based on electromagnetic principles. Understanding electromagnetism is crucial for electricians, as it allows them to harness and manipulate electrical energy efficiently and effectively in various applications.
