Electromagnetism is a branch of physics that studies the interactions between electricity and magnetism. It is based on the idea that electric and magnetic fields are related and can influence each other.
Moving electric charges generate magnetic fields, and in turn, magnetic fields can induce electric currents.
This electromagnetic interaction is fundamental for explaining phenomena such as electricity generation, the operation of electric motors, the propagation of electromagnetic waves (such as light), and many other technological applications that we use in our daily lives.
