👉 Electromagnetism is the branch of physics that studies the interactions between electrically charged particles and the electromagnetic field, which is a fundamental force of nature that combines electricity and magnetism. It is described by Maxwell's equations, which unify the previously separate theories of electricity and magnetism into a single coherent framework. These equations explain how electric charges create electric fields, how magnetic fields are generated by moving charges (currents), and how changing electric fields induce magnetic fields, and vice versa. This interplay gives rise to electromagnetic waves, such as light, radio waves, and X-rays, which propagate through space at the speed of light. Electromagnetism is crucial in understanding and applying technologies ranging from electric motors and generators to wireless communication and medical imaging.
