This document outlines the topics covered in 5 units on electromagnetism: Unit I covers vector algebra and static electric fields including Coulomb's law, electric flux density, and Gauss's law. Unit II discusses conductors, dielectrics, polarization, and capacitors. Unit III covers Biot-Savart law, magnetic field intensity, and Ampere's circuital law. Unit IV examines magnetic forces, materials, inductance, and energy stored in magnetic fields. Unit V looks at time-varying fields, Faraday's law, Maxwell's equations, and the electromagnetic spectrum.
