Electromagnetism is the branch of physics that deals with the study of electric and magnetic fields and how they interact with each other. It encompasses the forces that result when electric charges are in motion, such as when an electric current flows through a wire, producing a magnetic field around it.
This principle is utilised in many everyday technologies, including electromagnets, electric motors, and transformers.
At the GCSE level, students explore how changing magnetic fields can induce electric currents and vice versa, understanding the fundamental ideas that unify electricity and magnetism into a single force.
