SHS3 Physics · Semester 2 Week 6: Electromagnetic Induction & Applications

Lesson notes

Learning Objectives

Indicator: 3.3.3.LI.1 - Explain electromagnetic induction.

By the end of the lesson, learners can:

Define electromagnetic induction as the production of an electromotive force (emf) in a conductor when the magnetic field around it changes.
Describe the essential conditions required for electromagnetic induction to occur, namely relative motion between a conductor and a magnetic field.
Explain the role of the magnetic field, conductor and motion in generating an induced current, with reference to everyday applications such as generators and bicycle dynamos.
Discuss the historical contributions of Michael Faraday, Joseph Henry, and contemporary African and female scientists to the discovery and application of electromagnetic induction.
Identify practical applications of electromagnetic induction in daily life in Ghana, including electricity generation at Akosombo and thermal plants.
