The direction of induced current is obtained by:
- Fleming's left hand rule
- Clock rule
- Right hand thumb rule
- Fleming's right hand rule
Answer
Fleming's right hand rule
Reason — The direction of induced current is obtained by Fleming's right hand rule.
Fleming's right hand rule — Stretch the thumb, central finger and forefinger of your right hand mutually perpendicular to each other. If the forefinger indicates the direction of magnetic field and the thumb indicates the direction of motion of the conductor, then the central finger will indicate the direction of induced current.
