What you'll learn

  1. Twist a loop: Torque on a loop: τ = N I A B sin θ
  2. Two coils, one moment: Magnetic moment: μ = N I A
  3. Opposite loops: Moments add as arrows
  4. Turn it slowly: Work to turn a magnet slowly
  5. Energy from a torque: Torque and energy from one M B
  6. Flip it over: Stable and unstable positions
  7. Lift one edge: Tip a coil about one edge
  8. Two swinging magnets: Swinging magnets: T = 2π √(I / M B)
