What you'll learn

  1. Wind for 10 V: The peak emf of a spinning coil
  2. One turn a second: Turns each second into ω
  3. Where it peaks: Largest emf where the flux is zero
  4. Stop at 60°: The emf at any angle
  5. Mains frequency: One turn, one cycle
  6. The emf at a moment: The emf as time goes on
