H2 Physics: Electromagnetic Induction structured questions
Written practice in Faraday's and Lenz's laws, motional e.m.f., transformers, flux-linkage data and eddy currents. Five questions are selected for each attempt.
Learning objectives
- Use magnetic flux and flux-linkage relationships.
- Apply Faraday's and Lenz's laws to induced e.m.f. and direction.
- Explain simple applications of electromagnetic induction, including motional e.m.f. and eddy currents.
- Explain simple iron-core transformer operation and apply ideal transformer ratios.
