Unit Code: PHY502

Unit Title: Electrical Physics

This unit will introduce you to the branch of physics concerned with electric and magnetic phenomena. The laws of electricity and magnetism have a central role in the operation of such devices as radios, televisions, electric motors, computers, high-energy accelerators, and other electronic devices. More fundamentally, the interatomic and intermolecular forces responsible for the formation of solids and liquids are electric in origin. Furthermore, such forces as the pushes and pulls between objects and the elastic force in a spring arise from electric forces at the atomic level. The unit serves as an introduction to electricity and magnetism and begins with electric charge in matter, the forces between charges, the electric field, Gauss’s Law, and the electric potential. Electric current and resistance are introduced, and then the programme moves to the magnetic field, Ampere’s Law, and induction.
