Dear Students,
This module aims to introduce basic concepts in electricity and magnetism. It also provides you with an understanding of the physics embodied in Maxwell’s equations. It is intended to lay the foundation before you encounter hard-core engineering subjects. The module prepares you for future modules in the second, third and fourth years dealing with wave propagation and electromagnetism phenomena.
Intended Learning Outcomes
Having successfully completed the module, you should be able to:
- Demonstrate more understanding about the concepts of charge, field and flux;
- Understand and outline the interaction between electrostatic or magnetic fields and different classes of material (dielectric materials, dia-, para-, and ferro-magnetic materials);
- Understand the phenomena of capacitors and inductance;
- Understand the behavior of electricity generators and electric motors, and be able to find the energy in simple magnetic fields;
- Understand the phenomenon of resistance and be able to calculate the current and potential distributions in simple DC networks;
- Understand the significance of all quantities that appear in Maxwell’s equations, and describe how these equations lead to electromagnetic waves.

Introduction to Unit 1
We begin our study of electromagnetism by discussing the concepts of electric charge. We will find that the electric charge is quantized and conserved, but we have control over how things get charged. We will study the interaction of electric charges at rest (electrostatics) and the governing Coulomb’s law using the concept of electric charge and fields. Finally, we will interpret the Gauss’s law for electrostatics and apply it in some engineering situations.
Intended Learning Outcomes
Having successfully completed this section, you should be able to
- Recognize the fundamental electric nature, with electric charge as an intrinsic property;
- Graphically and quantitatively describe the electric fields created by points and/or continuous charge distributions;
- Describe the behavior of the electric force using Coulomb’s law;
- Interpret Gauss’s law for the electric field and apply it in some situations.

Introduction to Unit 2
Every time you turn on a light or an electric motor, you are making the use of electrical energy, a familiar part of our life, and an indispensable ingredient of our technology. In this section, we will learn about electric energy and how it is stored in capacitors. We introduce this study with work and energy in a mechanical context, then we combine these concepts with what we learned about electric charge, coulomb’s law, an electric field to define the electric energy. Capacitors which are devices that can store electric potential energy in an electric field will be discussed and related calculations will be studied within this section.

Introduction to Unit 5
Everybody uses magnetic forces. Magnetic forces are involved in electric motors and generators, TV, microwave ovens, computer printers, disk drivers, and others. Without magnetic fields, we wouldn’t even see, as the light itself results from an interaction between magnetism and electricity. The most familiar aspects of magnetism are those associated with permanent magnets, which unmagnetized iron objects and can also attract or repel other magnets. This section examines the forces that act on moving charges and on current-carrying wires in the presence of magnetic fields.
Intended Learning Outcomes
Having successfully completed this section, you should be able to
- Describe the fundamental nature of magnetism and its relation to electric charge;
- Understand the interaction between magnetism and electricity and use it to calculate magnetic forces on electric currents;
- Explain the relation between the magnetic field and magnetic force;
- Calculate the motion of charged particles in magnetic fields.

Introduction to Unit 6
In the previous section, we discussed the magnetic force exerted on a charged particle moving in a magnetic field. To complete the discussion on the magnetic interaction, this section explored the origin of the magnetic fields. We begin our study with the Biot-Savart law and its applications. Then, we will introduce Ampere’s law, which plays a role in magnetism analogous to the role of Gauss’s law in electrostatics. Before discussing the behavior of magnetic fields in some materials, we will discuss the magnetic fields generated by some current structures, and illustrate the Gauss’s law in magnetism.
Intended Learning Outcomes
Having successfully completed this section, you should be able to
- Understand the Biot-Savart law and use it to describe the magnetic field produced by current-carrying wire for various geometries;
- Demonstrate knowledge on nature magnetic fields produced by a single moving charged particle;
- Quantitatively explain the origin of interaction between current-carrying wires;
- Use the Ampere’s law to calculate the magnetic field of the symmetric current distribution
- Interpret Gauss’s law for the magnetic field.

Introduction to Unit 7
Almost every modern device or machine, from computers to power drills, has an electric circuit at its heart. We learned that electromotive force (emf) is required for current to flow in a circuit. For that purpose, we took the source of emf to be a battery. But for the vast variety of electric devices that are used in industries and in the home, the emf is not a battery but an electric generator. Such generators produce electric energy by converting other forms of energy into electrical energy. In most cases, this energy conversion is done through the phenomenon known as electromagnetic induction. In this section, we will learn about induced emf.
Intended Learning Outcomes
Having successfully completed this section, you should be able to
- Explain the phenomenon of electromagnetic induction;
- Use Faraday’s law to calculate induced electromotive forces and currents;
- Describe how induction is consistent with energy conservation, and find the direction of induced currents;
- Explain inductance, and analyze simple circuits involving inductors;
- Recognize the broader meaning of Faraday’s law as it relates to electric and magnetic fields.

On Electromagnetic induction & Inductance

Introduction to Unit 8
Until now we have considered electric circuits energized by steady sources (DC). However, many circuits involve time-varying electrical quantities. We consider these circuits as alternating currents (AC). Any appliance that you plug into a wall outlet use AC, and many battery-powered devices, such as cell phones, portable radio receiver, make use of the DC supplied by the battery to crease or amplify alternating currents. This section discusses the AC. We will start with a simple series of circuits that contain resistors, capacitors, and inductors that are driven by a sinusoidal voltage. Most of the principle that we discussed in previous sections are applicable, along with several new concepts related to the circuit behavior of resistance, induction, and capacitors.
Intended Learning Outcomes
Having successfully completed this section, you should be able to
- Characterize AC circuit quantities in terms of amplitude, frequency, and phase;
- Explain the relationship between current and voltage in resistors, capacitors, and inductors, and describe these relationships using equations and phasor diagrams;
- Quantitatively describe oscillations in AC circuits;
- Determine the amount of power flowing into or out AC circuits;
- Describe the operation of transformers and power supplies.

Alternating current circuit

Introduction to Unit 9
Humans have been asking the nature of light for centuries. However, no satisfactory answer was given until electricity and magnetism were unified into electromagnetism, as described by Maxwell’s equations. Energy from the sun (including visible light) reaches us by means of electromagnetic waves. Electromagnetic waves occur in an astonishing variety of physical situations, such as TV and radio transmissions, cellular phones, microwave oscillators, x-ray machines, and radioactive nuclei. So, it worth making a careful study of them. In this section, we will use Maxwell’s equations as the theoretical basis for understanding electromagnetic waves.
Intended Learning Outcomes
Having successfully completed this section, you should be able to:
- State the four fundamental equations that govern all electromagnetic phenomena;
- Describe electromagnetic waves in terms of frequency, wavelength, amplitude, and speed;
- Recognize the wide range of frequencies and wavelengths that make up electromagnetic spectrum;
- Explain how electromagnetic waves are produced;
- Calculate energy and power carried by electromagnetic waves.
