29  Module 6: Electromagnetism

29.1 Overview

Electromagnetism links electric and magnetic fields, and shows how forces on charges and currents underpin modern technology.

29.2 Inquiry questions

• What happens to stationary and moving charged particles when they interact with an electric or magnetic field?
• Under what circumstances is a force produced on a current-carrying conductor in a magnetic field?
• How are electric and magnetic fields related?
• How has knowledge about the Motor Effect been applied to technological advances?

29.3 Outcomes (syllabus wording)
