| Lesson Topic: Describe the forces between magnetic poles and between magnets and magnetic materials, including the use of the terms north pole (N pole), south pole (S pole), attraction and repulsion, magnetised and unmagnetised |
Learning Objective/s:
- Describe the forces between magnetic poles using the terms north pole, south pole, attraction and repulsion.
- Explain how magnetic materials become magnetised and differentiate between magnetised and unmagnetised states.
- Identify the behaviour of ferromagnetic, paramagnetic and diamagnetic materials in a magnetic field.
- Apply the concepts to predict the interaction between magnets and common materials.
|
Materials Needed:
- Bar magnets (at least two)
- Iron nails or small ferromagnetic pieces
- Compass
- Worksheet/handout with summary table
- Projector or interactive whiteboard
- Safety goggles (optional)
|
Introduction:
Have you ever wondered why a compass needle always points north? You already know that magnets have north and south poles. Today you will discover how those poles interact and how ordinary metals can become magnetised. Success will be measured by your ability to describe attraction, repulsion and the magnetised state of materials.

Lesson Structure:
- Do‑now (5'): Quick written question – “Give an everyday example of a magnet attracting or repelling something.”
- Mini‑lecture (10'): Introduce terminology, pole‑strength formula and field‑line concept using the projector.
- Demo 1 (8'): Two bar magnets – observe repulsion of like poles and attraction of opposite poles.
- Demo 2 (8'): Iron nail near a magnet – note induced magnetisation and attraction to either pole.
- Demo 3 (7'): Compass placed near a magnet – discuss direction of field lines.
- Guided activity (12'): Complete worksheet – fill the summary table and classify materials as ferromagnetic, paramagnetic or diamagnetic.
- Check for understanding (5'): Exit‑ticket cards – students write one example of attraction and one of repulsion.
|
Conclusion:
We revisited how like poles repel, opposite poles attract, and how ferromagnetic materials become magnetised in a magnetic field. To finish, write one real‑world example of magnetic attraction and one of repulsion on your exit ticket. For homework, complete the textbook questions on magnetic forces and prepare to discuss magnetic shielding in the next lesson.
