Electromagnetism

Electricity and Magnetism are inextricably linked.  Where there is an electric current, there is always a magnetic field.  Conversely a changing magnetic field next to a wire always induces a voltage.  These notes are designed to review what you covered at A-level.  However there is related content that is not on every syllabus, which it is important to be aware of.  ("What?  Never done the Hall Effect?   Good Lord, man!")  The understanding of magnetic properties is important part of the study of electric motors and transformers.
