Sample exercises
A north pole approaches a south pole. What is expected?
- The poles disappear
- Attraction
- Repulsion only
Answer and explanation
Attraction
Unlike poles attract.
Which statement is the best testable prediction?
- Every metal is strongly attracted.
- This iron paper clip may be attracted; test it at the same gap.
- Colour alone decides attraction.
Answer and explanation
This iron paper clip may be attracted; test it at the same gap.
Material and experimental conditions matter; all-metal claims are too broad.
Must a magnet touch an iron object to exert a force on it?
- Only if the object is red
- Yes, always
- No
Answer and explanation
No
Magnetic forces can act across a gap.
Why should two objects be tested at the same distance from a magnet?
Answer and explanation
Distance affects the interaction, so it should not change during the comparison.
Credit a controlled variable and its purpose.
A coin is not attracted. Does that prove the magnet is broken?
Answer and explanation
No. Some metals are not strongly attracted; test a known suitable object too.
Accept using a comparison object rather than assuming all metals behave alike.

Grades 2–5Fields, motors and induced effects
Connect magnetic fields with currents without treating field lines as wires.
Grades 9–12Fields, motors and induced effects · Revision sheet
Connect magnetic fields with currents without treating field lines as wires.
Grades 9–12Ideal transformers and conservation
Use turns ratios and distinguish the ideal AC model from real losses.
Grades 10–12Ideal transformers and conservation · Revision sheet
Use turns ratios and distinguish the ideal AC model from real losses.
Grades 10–12Ideal transformer voltage ratio
This ideal transformer model uses alternating voltage; it is not a mains-wiring activity.
Grades 10–12Force on a perpendicular current-carrying wire
The straight active wire length is perpendicular to the uniform magnetic field.
Grades 11–12Average induced emf
Use flux change per turn; the question asks magnitude, not the direction set by Lenz’s law.
