TL;DR
The 2026 SEAB Physics syllabus lists resistance determination, magnetic effect of current, and electromagnetic induction in the Paper 3 practical techniques list (items 16–18).
MMO marks depend on clean circuit assembly, accurate meter readings, and safe handling of power supplies.
ACE answers should connect gradients and induced-voltage trends to Ohm’s law, Fleming’s left-hand rule, and Faraday’s law while acknowledging internal resistance, heating, and flux leakage.

1 | What SEAB expects you to demonstrate
- Resistance measurements (item 16): Construct series/parallel circuits, record – pairs, and compute resistance or resistivity (SEAB 2026 Physics syllabus).
- Magnetic effect of current (item 17): Use compasses, iron filings, or force-on-conductor setups to show how current produces magnetic fields; expect to vary current or coil turns.
- Electromagnetic induction (item 18): Move magnets through coils or spin coils in magnetic fields; measure induced emf with sensitive meters, possibly using data-loggers (the apparatus list states candidates should be familiar with data-loggers and Planning may include them; SEAB 2026 Physics syllabus).
