SHS3 Physics · Semester 2 Week 7: Electromagnetic Induction & Applications

Lesson notes

Learning Objectives

Indicator: 3.3.3.LI.2 - Using experimentation, verify the laws of electromagnetic induction.

By the end of the lesson, learners can:

Describe the key observations from Faraday’s experiments that led to the formulation of Faraday’s law of electromagnetic induction.
State Faraday’s law of electromagnetic induction and apply it to calculate induced emf given the rate of change of magnetic flux linkage.
Describe the observations from Lenz’s experiments and state Lenz’s law in their own words.
Use Lenz’s law to determine the direction of an induced current in a simple experimental setup.
Perform or simulate simple laboratory experiments to verify both laws of electromagnetic induction, and communicate their findings clearly in groups.
