O-Level Physics Electricity & Magnetism Practical Manual (Paper 3)

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 $I$ - $V$ 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;

Practical course completion-record note

For practical, lab, and experiment courses, Eclat Institute maintains centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.

• For SEAB private-candidate declarations, the key evidence is the centre's attendance or completion record, not a government-issued certificate.
• This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
• Recognition (if any) is determined by the receiving school, institution, or employer.
• For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or attend a practical course and complete it before the practical paper date.
