Fleming’s right‑hand rule is a mnemonic for the direction of induced current in a conductor moving in a magnetic field (used for generators / electromagnetic induction).
How to use it
- Hold your right hand so the thumb, first (index) finger and second (middle) finger are mutually perpendicular (at right angles).
- Thumb = direction of motion of the conductor (or velocity of the conductor relative to the magnetic field).
- First/index finger = direction of the magnetic field (from North to South).
- Middle finger = direction of the induced (conventional) current.
Notes
- “Conventional” current means the direction positive charges would move; electron flow is opposite.
- Fleming’s left‑hand rule is the companion for motors (given current and field, it gives force/motion).
- This rule corresponds to the vector relation v × B (motion cross field) giving the direction of induced emf/force on positive charges.
