Fleming's Left-Hand Rule: "FBI" — Force (thumb), B-field (first finger), I-current (second finger). Hold your left hand with all three at right angles to each other.
Left hand vs Right hand:
- Left hand = motor effect (force on conductor). Remember: Left = Load bearing / Lifting things (motors lift and move)
- Right hand grip rule = field direction around a wire
DC Motor components — CMBS:
- Coil (carries current)
- Magnets (provide field)
- Brushes (connect supply)
- Split-ring commutator (reverses current)
