What you'll learn

  1. Push on a wire: The push on a current: F = B I L
  2. Float the rod: Float a rod: B I L = m g
  3. A wire from its resistance: Length from resistance, then B I L = m g
  4. Half a circle: A bent wire feels the push of its chord
  5. Float the half circle: Float a bent wire: B I (2R) = m g
  6. Where B grows: A loop in a field that grows
  7. Drag the rod: Work against a push that changes
