Lesson Topic: Describe induced magnetism
Learning Objective/s:
  • Describe the process of induced magnetism in ferromagnetic materials.
  • Explain how magnetic domains align under an external magnetic field.
  • Analyse factors that affect the strength of induced magnetism.
  • Compare induced magnets with permanent magnets and electromagnets.
  • Predict the behaviour of common objects (paperclip, nail) when exposed to a magnetic field.
Materials Needed:
  • Bar magnet
  • Iron nails or steel paperclips
  • Solenoid with power supply
  • Whiteboard and markers
  • Projector or interactive display
  • Worksheet with diagram and questions
 Introduction:
Begin with a quick demonstration: hold a bar magnet near a paperclip and ask students what they observe. Recall that ferromagnetic materials contain magnetic domains that can align. Explain that today’s success criteria are to describe how an external field induces temporary magnetism and to compare it with permanent magnets.
Lesson Structure:
  1. Do‑now (5’) – Students write one example of a magnet they encounter daily; share responses.
  2. Demonstration (10’) – Teacher shows magnet‑paperclip and solenoid‑nail demos, highlighting domain alignment.
  3. Direct instruction (12’) – Explain domain theory, temporary magnetisation, and influencing factors using slides.
  4. Guided practice (10’) – Pairs label a diagram of an induced magnet and answer worksheet questions.
  5. Comparison activity (8’) – Small‑group discussion comparing permanent, induced, and electromagnets using the provided table.
  6. Check for understanding (5’) – Quick quiz via clickers or show of hands on key concepts.
  7. Summary & exit ticket (5’) – Students write one sentence summarising induced magnetism and one lingering question.
Conclusion:
Review the key steps of domain alignment and the temporary nature of induced magnets. Invite a few students to share their exit‑ticket sentences, reinforcing the success criteria. Assign homework to research a real‑world application of induced magnetism, such as magnetic separation in recycling.
