Magnetic Fields

磁场

Description

Describe magnetic poles (north and south), explain attraction and repulsion between poles, describe magnetic field lines plotted using a compass, and explain the Earth's magnetic field and its practical uses

Mastery Evidence

✓ States the rule for attraction and repulsion of magnetic poles
✓ Draws the magnetic field pattern around a bar magnet from memory or compass readings
✓ Explains why a compass needle points north
✓ Explains that the Earth has a magnetic field and describes how it is used for navigation

Assessment Prompt

If your child used a compass and iron filings to map the magnetic field around a bar magnet, could they describe what pattern the field lines make and explain why a compass needle always points roughly north?
