  • Generating Electricity
    • Explain qualitatively the factors affecting the emf induced in a coil when there is relative motion between the coild and a permanent magnet and when there is a change of current in a primary coil linked with it.
    • Recognise and use the expression          E = -d (N  ) / dt
    • Explain how E=-d(N  )/dt is a consequence of Faraday's and Lenz's laws.
