IGCSE Course book
By the end of the lesson, students will be able to:
1. Define electromagnetic induction and explain how it generates electricity.
2. Describe how the movement of a conductor in a magnetic field induces an EMF.
3. Identify factors that affect the size of the induced EMF.
4. Explain the relationship between magnetic field lines and induction.
5. Apply the concept to real-life examples such as power generation.
Unit objective
Students will understand how electricity can be generated using the principle of
electromagnetic induction and how changing magnetic fields induce an EMF in a conductor.
Vocabulary
Electromagnetic Induction, Induced EMF (Electromotive Force), Magnetic Flux, Coil,
Conductor, Magnetic Field Lines, Generator, Faraday’s Law, Lenz’s Law
Main Teaching
Starter (3 min)
Pose the question: 'How do power stations generate electricity?'
→ Let students discuss and then share their ideas with the class.

“Today, we’ll learn how electricity can be generated without batteries by moving a wire
through a magnetic field — this is called electromagnetic induction. By the end, you’ll be
able to explain this process and how we can increase the voltage produced.”
Explore the topic
1. Explain Faraday’s Law of Induction:
- When a conductor cuts across magnetic field lines, an EMF is induced.
- No current is induced unless the circuit is complete.
2. Demonstrate:
- Use a magnet and coil connected to a galvanometer.
- Move the magnet in and out of the coil — show needle deflection.
- Reverse the magnet — explain direction of current (Lenz’s Law).
3. Factors Affecting EMF:
- Speed of movement
- Strength of magnetic field
- Number of turns in the coil
4. Induction and Field Lines:
- Magnetic field lines represent the direction and strength of the field.
- Induction occurs when field lines are cut by the conductor.

Hands-on (Group Work / Stations):
- Rotate students through setups:
- Moving a magnet in and out of a coil
- Rotating a coil in a magnetic field (simple hand generator)
- Varying number of coil turns and observing galvanometer response

Plenary / Review
Home Work
(5 min)
Students record:
- Observation of current (deflection)
- Direction changes
- EMF increase with speed, field strength, and number of turns
Students complete short-answer questions:
1. Define electromagnetic induction.
2. What causes the current when a magnet is pushed into a coil?
3. List three ways to increase the induced EMF.
4. Sketch magnetic field lines and show a coil cutting through them.
Reflect on the Verse (Surah Al-Nur 24:35):
“Allah is the Light of the heavens and the earth…”
Just as Allah gives physical light, He also gives us guidance through science and knowledge.
The ability to generate electricity and use it for human benefit reflects the power of Allah’s
creation and our responsibility to use it wisely.
Multiple-choice or true/false questions:
- Electromagnetic induction definition
- Direction of current when magnet is moved
- Ways to increase EMF
- Role of magnetic field lines
Exit Question: “One way to increase the induced EMF is __________?”
Research and write a short report (half page) on how electricity is generated in:
- a hydroelectric power station OR
- a wind turbine using electromagnetic induction principles
Assessment Date (if any) N/A
What went well:
- Were students engaged in hands-on activity?
- Did most achieve the learning objectives?
What needs improvement:
- Did any students struggle with abstract concepts?
Reflection and Evaluation - Was the link to real-life applications clear?
Plan for next lesson:
- Introduce AC vs DC generators and Transformer basics.
