What you'll learn

  1. Ramp the current: A changing current makes an emf in its own coil
  2. Find L: Measure L from the kick
  3. Light the neon: A fast switch-off gives a big kick
  4. One instant: The loop rule with a coil
  5. Walk the branch: Walk a branch with a coil
  6. Induction coil: The other coil's kick makes the spark
