Read Magnetisation poles and magnetic materials
This SOF ISO pattern tests apply magnetic principles. Read the condition carefully, then use the method below before you solve.
Electricity questions depend on identifying charge, a conducting path and the condition that controls current or magnetic effect.
Magnetic effects have two poles and a direction
Like poles repel · unlike poles attract
Like poles repel and unlike poles attract. Keep the field direction and the material’s magnetic property separate.
Find the tested idea
Identify the material, change or observable property first; this decides the scientific rule to use.
Work from the evidence
Use the experiment or stated observation as evidence. Compare each option with the property, particle model or reaction condition in the stem.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
