20  Module 4: Electricity and Magnetism

20.1 Overview

Module 4 introduces electric charge, fields, circuits, and magnetic effects. It links microscopic charge motion to measurable currents and explores how fields store and transfer energy.

20.2 Inquiry questions

  • How do electric charges create forces and fields?
  • How does charge flow through circuits to transfer energy?
  • How do currents create magnetic fields?
