Electromagnetism and Light module (EG21008)

Electromagnetism is the physical interaction between electric charges, magnetic moments, and electromagnetic fields. We will see how electromagnetism is integral to the devices and technology we use every day.

We will see how important electro-magnetism is to the modern world. Your television, phone, and radio all rely on electromagnetism, using electricity, magnetism, or light to work.

Electric and magnetic fields can be either static, like the Earth's magnetic field, or changing like in alternating current (AC) circuits.

This module will explore electromagnetism and light, as well as sub-topics such as Coulomb's law, Gauss's law, magnetic fields, electromagnetic induction etc.

What you will learn

In this module, you will:

• review Coulomb’s Law, electric fields, and electric potential
• learn about Gauss’s law
• study magnetic fields and forces and sources of magnetic fields
• learn about electromagnetic induction and alternating current circuits
• explore the nature and propagation of light, including polarization, interference, and diffraction

By the end of the module you will be able to:

• name and describe a range of electrostatic and magnetic effects
• describe the concepts of electromagnetic induction, inductance, and electromagnetic energy
• analyse alternating current circuits making use of inductors, capacitors, and resistors
• use electromagnetic waves to develop Maxwell’s description of electromagnetism
• apply the concept of an electromagnetic wave to the understanding of light and its interactions
