What you'll learn

  1. Light the bulb: A moving rod makes an emf
  2. Keep it moving: Magnetic drag on a moving rod
  3. A slanted rod: Only the part across the motion cuts
  4. V-shaped rails: A cut length that grows
  5. Through a strip: Emf needs a changing flux
  6. Pull it out: Your work becomes heat
  7. Drop on rails: Terminal speed on rails
  8. Across a triangle: A cut length that changes with position
  9. Coast into the field: A drag that falls with speed
  10. Rails with a coil: A rod as the cell of an RL circuit
