Explanation
Permanent magnets maintain their field; induced magnetism develops in a magnetic material placed in a field and largely disappears for a soft induced sample when removed. Pole interactions and material attraction are different tests; not all metals are magnetic.
Concepts, equations and units: N/S poles; unlike attract/like repel; induced magnetism attracts; iron,steel,cobalt,nickel; force N qualitatively.
Prediction, demonstration and game exercise
Predict, observe, explain
Compare a permanent magnet with an iron sample in and out of the field.
Planned learner game exercise
Sort materials and test labelled pole configurations; predict induction and loss of magnetism.
Independent practice
Explain three magnet interactions and identify a valid test for a permanent magnet.
Original practice example · Shared
Predict interactions for N–N and N–S poles of permanent magnets.
Show working and model answer
Working / reasoning
Like poles repel; unlike poles attract.
Answer
N–N repels; N–S attracts.
Exit check and success criteria
Three predictions correct and induction explanation does not claim every metal is magnetic.
During practice, compare the prediction with evidence and give an error-specific prompt. The exit item uses a fresh context or fresh values, answered independently.
Misconceptions, practical links and mastery
Check these misconceptions
All metals are attracted; induced iron repels either pole; breaking a magnet isolates a single pole.
Practical preparation
Optional magnets/material observations; no RP.
Virtual preparation and revision only. Required hands-on activities and school records remain separate.
Proposed mastery
0: not yet evidenced. 1: supported. 2: independent exit criteria met. 3: successful changed-context transfer. Advance at 2; revisit with fresh retrieval. These are not GCSE grades.
